All argument aside about whether these products are worthwhile (hopefully) I am having a very strange and random technical problem with one of these boxes and I know in the past there were folks on NANOG who used them, if possible can anyone who falls into that category contact me off-list please? thanks, -Drew

That obviously means that AS_SET would not be necessary, but as an effect rather than the cause. One could also dump the AGGREGATOR and the AS4_AGGREGATOR attributes in the nearest waste bin. AND it would simplify the merging of AS_PATH and AS4_PATH attributes, which is a complete dogs breakfast... because it tries, in vain, to finesse its way out of the problem of an AS2 speaker aggregating routes with AS4_PATHs ! [Made even more galling by the sure and certain knowledge that aggregated routes are as exquisitely rare as they are useful.] And what about the truly, madly, deeply useless AS_CONFED_SET ? [A carbuncle's carbuncle if ever I saw one.] Vote early and vote often, say I. Chris

Cisco Security Advisory: Cisco IOS Software Network Address Translation Vulnerabilities
by Cisco Systems Product Security Incident Response Team 22 Sep '10

22 Sep '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Cisco IOS Software Network Address Translation Vulnerabilities Advisory ID: cisco-sa-20100922-nat http://www.cisco.com/warp/public/707/cisco-sa-20100922-nat.shtml Revision 1.0 For Public Release 2010 September 22 1600 UTC (GMT) - --------------------------------------------------------------------- Summary ======= The Cisco IOS Software Network Address Translation functionality contains three denial of service (DoS) vulnerabilities. The first vulnerability is in the translation of Session Initiation Protocol (SIP) packets, the second vulnerability in the translation of H.323 packets and the third vulnerability is in the translation of H.225.0 call signaling for H.323 packets. Cisco has released free software updates that address these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20100922-nat.shtml Note: The September 22, 2010, Cisco IOS Software Security Advisory bundled publication includes six Cisco Security Advisories. Five of the advisories address vulnerabilities in Cisco IOS Software, and one advisory addresses vulnerabilities in Cisco Unified Communications Manager. Each advisory lists the releases that correct the vulnerability or vulnerabilities detailed in the advisory. The table at the following URL lists releases that correct all Cisco IOS Software vulnerabilities that have been published on September 22, 2010, or earlier: http://www.cisco.com/warp/public/707/cisco-sa-20100922-bundle.shtml Individual publication links are in "Cisco Event Response: Semiannual Cisco IOS Software Security Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep10.html Affected Products ================= Vulnerable Products +------------------ Cisco devices running Cisco IOS Software that are configured for NAT and that support NAT for SIP, H.323, or H.225.0 call signaling for H.323 packets are affected. To verify whether NAT is enabled on a Cisco IOS device log in to the device and issue the show ip nat statistics command. The following example shows a device that is configured with NAT: Router#show ip nat statistics Total translations: 2 (0 static, 2 dynamic; 0 extended) Outside interfaces: Serial0 Inside interfaces: Ethernet1 Hits: 135 Misses: 5 Expired translations: 2 Dynamic mappings: -- Inside Source access-list 1 pool mypool refcount 2 pool mypool: netmask 255.255.255.0 start 192.168.10.1 end 192.168.10.254 type generic, total addresses 14, allocated 2 (14%), misses 0 Alternatively, administrators can use the show running-config | include ip nat command to verify if NAT has been enabled on the router interfaces. For NAT to be enabled in a router either the ip nat inside and ip nat outside commands must be present in different interfaces or, in the case of NAT Virtual Interface, if the ip nat enable interface command is present. In order to determine the software that runs on a Cisco IOS product, log in to the device and issue the show version command to display the system banner. Cisco IOS software identifies itself as "Internetwork Operating System Software" or simply "IOS." On the next line of output, the image name displays between parentheses, followed by "Version" and the Cisco IOS release name. Other Cisco devices do not have the show version command or give different output. The following example shows output from a device that runs an IOS image: Router> show version Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2009 by Cisco Systems, Inc. Compiled Wed 02-Dec-09 17:17 by prod_rel_team <More output removed for brevity> Products Confirmed Not Vulnerable +-------------------------------- Cisco IOS devices not explicitly configured for NAT are not vulnerable. Cisco IOS XE Software is not affected by these vulnerabilities. Cisco IOS XR Software is not affected by these vulnerabilities. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The three vulnerabilities are triggered by transit traffic that needs to be processed by the NAT feature. Each vulnerability is independent of each other. NAT for SIP DoS Vulnerability +---------------------------- SIP is a popular signaling protocol that is used to manage voice and video calls across IP networks such as the Internet. SIP is responsible for handling all aspects of call setup and termination. Voice and video are the most popular types of sessions that SIP handles, but the protocol has the flexibility to accommodate other applications that require call setup and termination. NAT for SIP translates packets using UDP (port 5060) or TCP (port 5060) as the underlying transport protocol. The NAT for SIP DoS vulnerability can be exploited only with the use of UDP port 5060 packets. This vulnerability is documented in Cisco bug ID CSCtf17624 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2010-2831. NAT for H.323 DoS Vulnerability +------------------------------ H.323 is the International Telecommunication Union (ITU) standard for real-time multimedia communications and conferencing over packet-based (IP) networks. NAT for H.323 translates packets on TCP port 1720. There is a DoS vulnerability in the NAT procession of H.323 packets. The vulnerability does not require the completion of a TCP three-way handshake. This vulnerability is documented in Cisco bug ID CSCtf91428 and has been assigned Common Vulnerabilities and Exposures (CVE) IDs CVE-2010-2832. NAT for H.225.0 DoS vulnerability +-------------------------------- H.323 is the ITU standard for real-time multimedia communications and conferencing over packet-based (IP) networks. A subset of the H.323 standard is H.225.0, a standard used for call signaling protocols and media stream packetization over IP networks. NAT for H.225.0 translates packets on TCP port 1720. There is a DoS vulnerability in the NAT translation of H.225.0 call signaling for H.323 packets. This vulnerability is documented in Cisco bug ID CSCtd86472 and has been assigned Common Vulnerabilities and Exposures (CVE) IDs CVE-2010-2833. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score.

Cisco Security Advisory: Cisco IOS SSL VPN Vulnerability
by Cisco Systems Product Security Incident Response Team 22 Sep '10

22 Sep '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco IOS SSL VPN Vulnerability Advisory ID: cisco-sa-20100922-sslvpn http://www.cisco.com/warp/public/707/cisco-sa-20100922-sslvpn.shtml Revision 1.0 For Public Release 2010 September 22 1600 UTC (GMT) - --------------------------------------------------------------------- Summary ======= Cisco IOS Software contains a vulnerability when the Cisco IOS SSL VPN feature is configured with an HTTP redirect. Exploitation could allow a remote, unauthenticated user to cause a memory leak on the affected devices, that could result in a memory exhaustion condition that may cause device reloads, the inability to service new TCP connections, and other denial of service (DoS) conditions. Cisco has released free software updates that address this vulnerability. There is a workaround to mitigate this vulnerability. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20100922-sslvpn.shtml Note: The September 22, 2010, Cisco IOS Software Security Advisory bundled publication includes six Cisco Security Advisories. Five of the advisories address vulnerabilities in Cisco IOS Software, and one advisory addresses vulnerabilities in Cisco Unified Communications Manager. Each advisory lists the releases that correct the vulnerability or vulnerabilities detailed in the advisory. The table at the following URL lists releases that correct all Cisco IOS Software vulnerabilities that have been published on September 22, 2010, or earlier: http://www.cisco.com/warp/public/707/cisco-sa-20100922-bundle.shtml Individual publication links are in "Cisco Event Response: Semiannual Cisco IOS Software Security Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep10.html Affected Products ================= Vulnerable Products +------------------ Devices running affected versions of Cisco IOS Software are vulnerable if configured with SSL VPN and HTTP port redirection. The following methods may be used to confirm if the device is configured for Cisco IOS SSL VPNs and is vulnerable: If the output from show running-config | include webvpn contains "webvpn gateway <word>" then the device is supporting the Cisco IOS SSL VPN feature. A device is vulnerable if it has the inservice command in at least one of the "webvpn gateway" sections and is configured for HTTP port redirection. The following example shows a vulnerable device configured with Cisco IOS SSL VPN: Router#show running | section webvpn webvpn gateway Gateway ip address 10.1.1.1 port 443 http-redirect port 80 ssl trustpoint Gateway-TP inservice ! Router# A device that supports the Cisco IOS SSL VPN is not vulnerable if "webvpn gateway" is not configured. To determine the Cisco IOS Software release that is running on a Cisco product, administrators can log in to the device and issue the show version command to display the system banner. The system banner confirms that the device is running Cisco IOS Software by displaying text similar to "Cisco Internetwork Operating System Software" or "Cisco IOS Software." The image name displays in parentheses, followed by "Version" and the Cisco IOS Software release name. Other Cisco devices do not have the show version command or may provide different output. The following example identifies a Cisco product that is running Cisco IOS Software Release 12.4(20)T with an installed image name of C2800NM-ADVSECURITYK9-M: Router#show version Cisco IOS Software, 2800 Software (C2800NM-ADVSECURITYK9-M), Version 12.4(20)T, RELEASE SOFTWARE (fc3) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2008 by Cisco Systems, Inc. Compiled Thu 10-Jul-08 22:00 by prod_rel_team ! --- output truncated Additional information about Cisco IOS Software release naming conventions is available in "White Paper: Cisco IOS Reference Guide" at the following link: http://www.cisco.com/warp/public/620/1.html Products Confirmed Not Vulnerable +-------------------------------- The following products are not affected by this vulnerability: * Cisco ASA 5500 Series Adaptive Security Appliances * Cisco IOS XR Software * Cisco IOS XE Software No other Cisco products are currently known to be affected by this vulnerability. Details ======= The Cisco IOS SSL VPN feature provides remote access to enterprise sites to users anywhere on the Internet. The SSL VPN provides users with secure access to specific enterprise applications, such as e-mail and web browsing, without requiring them to have VPN client software installed on their end-user devices. Further information about Cisco IOS SSL VPN is available in the "Cisco IOS Software Release 12.4T SSL VPN feature guide" at the following link: http://www.cisco.com/en/US/docs/ios/12_4t/12_4t11/htwebvpn.html leavingcisco.com A device configured for SSL VPN with HTTP port redirection may leak transmission control blocks (TCBs) when processing an abnormally disconnected SSL session. Continued exploitation may cause the device to deplete memory resources, which could result in device reloads, the inability to service new TCP connections, and other DoS conditions. Authentication is not required to exploit this vulnerability. A complete TCP 3-way handshake is required to exploit this vulnerability. The memory leak can be detected by running the command show tcp brief as shown in the following example: Router#show tcp brief TCB Local Address Foreign Address (state) 468BBDC0 192.168.0.22.80 192.168.0.33.19794 CLOSEWAIT 482D4730 192.168.0.22.80 192.168.0.33.22092 CLOSEWAIT 482779A4 192.168.0.22.80 192.168.0.33.16978 CLOSEWAIT 4693DEBC 192.168.0.22.80 192.168.0.33.21580 CLOSEWAIT 482D3418 192.168.0.22.80 192.168.0.33.17244 CLOSEWAIT 482B8ACC 192.168.0.22.80 192.168.0.33.16564 CLOSEWAIT 46954EB0 192.168.0.22.80 192.168.0.33.19532 CLOSEWAIT 468BA9B8 192.168.0.22.80 192.168.0.33.15781 CLOSEWAIT 482908C4 192.168.0.22.80 192.168.0.33.19275 CLOSEWAIT 4829D66C 192.168.0.22.80 192.168.0.33.19314 CLOSEWAIT 468A2D94 192.168.0.22.80 192.168.0.33.14736 CLOSEWAIT 4688F590 192.168.0.22.80 192.168.0.33.18786 CLOSEWAIT 4693CBA4 192.168.0.22.80 192.168.0.33.12176 CLOSEWAIT 4829ABC4 192.168.0.22.80 192.168.0.33.39629 CLOSEWAIT 4691206C 192.168.0.22.80 192.168.0.33.17818 CLOSEWAIT 46868224 192.168.0.22.80 192.168.0.33.16774 CLOSEWAIT 4832BFAC 192.168.0.22.80 192.168.0.33.39883 CLOSEWAIT 482D10CC 192.168.0.22.80 192.168.0.33.13677 CLOSEWAIT 4829B120 192.168.0.22.80 192.168.0.33.20870 CLOSEWAIT 482862FC 192.168.0.22.80 192.168.0.33.17035 CLOSEWAIT 482EC13C 192.168.0.22.80 192.168.0.33.16053 CLOSEWAIT 482901D8 192.168.0.22.80 192.168.0.33.16200 CLOSEWAIT In the output above, the Transmission Control Blocks (TCBs) in the state CLOSEWAIT will not transition and represent a memory leak.

Cisco IOS XR System Software +--------------------------- Cisco IOS XR Software is not affected by the vulnerabilities disclosed in the September 22, 2010, Cisco IOS Software Security Advisory bundled publication. Workarounds =========== Disabling HTTP redirection for SSL VPN connections can be used as a workaround for this vulnerability. HTTP redirection for SSL VPN connections is disabled by executing the command no http-redirect port in webvpn gateway configuration mode. In addition, manually clearing the hung TCBs with the command clear tcp tcb * will transition the TCBs into a CLOSED state. After a time they will clear the CLOSED state and the memory will be released. Note: Clearing the TCB will clear both legitimate and hung connections, including remote connections to the device such as Telnet and SSH connections. The Cisco Applied Mitigation Bulletin (AMB) "Identifying and Mitigating Exploitation of the TCP State Manipulation Denial of Service Vulnerabilities in Multiple Cisco Products", available at http://www.cisco.com/warp/public/707/cisco-amb-20090908-tcp24.shtml, contains two mitigations (EEM scripts and SNMP) that can be used to detect and clear hung TCP connections. Embedded Event Manager (EEM) +--------------------------- A Cisco IOS Embedded Event Manager (EEM) policy that is based on Tool Command Language (Tcl) can be used on vulnerable Cisco IOS devices to identify and detect a hung, extended, or indefinite TCP connection that is caused by this vulnerability. The policy allows administrators to monitor TCP connections on a Cisco IOS device. When Cisco IOS EEM detects potential exploitation of this vulnerability, the policy can trigger a response by sending a syslog message or a Simple Network Management Protocol (SNMP) trap to clear the TCP connection. The example policy provided in this document is based on a Tcl script that monitors and parses the output from two commands at defined intervals, produces a syslog message when the monitor threshold reaches its configured value, and can reset the TCP connection. The Tcl script is available for download at the "Cisco Beyond: Embedded Event Manager (EEM) Scripting Community" at the following link: http://forums.cisco.com/eforum/servlet/EEM?page=eem&fn=script&scriptId=2041 A sample device configuration is provided below. ! !-- Location where the Tcl script will be stored ! event manager directory user policy disk0:/eem ! !-- Define variable and set the monitoring interval !-- as an integer (expressed in seconds) ! event manager environment EEM_MONITOR_INTERVAL 60 ! !-- Define variable and set the threshold value as !-- an integer for the number of retransmissions !-- that determine if the TCP connection is hung !-- (a recommended value to use is 15) ! event manager environment EEM_MONITOR_THRESHOLD 15 ! !-- Define variable and set the value to "yes" to !-- enable the clearing of hung TCP connections ! event manager environment EEM_MONITOR_CLEAR yes ! !-- Define variable and set to the TCP connection !-- state or states that script will monitor, which !-- can be a single state or a space-separated list !-- of states ! event manager environment EEM_MONITOR_STATES CLOSEWAIT ! !-- Register the script as a Cisco EEM policy ! event manager policy monitor-sockets.tcl !

Cisco Security Advisory: Cisco IOS Software H.323 Denial of Service Vulnerabilities
by Cisco Systems Product Security Incident Response Team 22 Sep '10

22 Sep '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Cisco IOS Software H.323 Denial of Service Vulnerabilities Advisory ID: cisco-sa-20100922-h323 http://www.cisco.com/warp/public/707/cisco-sa-20100922-h323.shtml Revision 1.0 For Public Release 2010 September 22 1600 UTC (GMT) - --------------------------------------------------------------------- Summary ======= The H.323 implementation in Cisco IOS Software contains two vulnerabilities that may be exploited remotely to cause a denial of service (DoS) condition on a device that is running a vulnerable version of Cisco IOS Software. Cisco has released free software updates that address these vulnerabilities. There are no workarounds to mitigate these vulnerabilities other than disabling H.323 on the vulnerable device. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20100922-h323.shtml Note: The September 22, 2010, Cisco IOS Software Security Advisory bundled publication includes six Cisco Security Advisories. Five of the advisories address vulnerabilities in Cisco IOS Software, and one advisory addresses vulnerabilities in Cisco Unified Communications Manager. Each advisory lists the releases that correct the vulnerability or vulnerabilities detailed in the advisory. The table at the following URL lists releases that correct all Cisco IOS Software vulnerabilities that have been published on September 22, 2010, or earlier: http://www.cisco.com/warp/public/707/cisco-sa-20100922-bundle.shtml Individual publication links are in "Cisco Event Response: Semiannual Cisco IOS Software Security Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep10.html Affected Products ================= These vulnerabilities only affect devices that are running Cisco IOS Software with H.323 voice services enabled. Vulnerable Products +------------------ Cisco devices that are running affected Cisco IOS Software versions that are configured to process H.323 messages are affected by these vulnerabilities. H.323 is not enabled by default. To determine if the Cisco IOS Software device is running H.323 services, issue the show process cpu | include H323 command, as shown in this example: Router# show process cpu | include H323 249 16000 3 5333 0.00% 0.00% 0.00% 0 CCH323_CT 250 0 1 0 0.00% 0.00% 0.00% 0 CCH323_DNS Router# In the previous example the processes CCH323_CT and CCH323_DNS are running on the device; therefore, the device is listening to H.323 messages. The device is vulnerable if any of these processes (or similar) are active. Note: Creating a dial peer by issuing the dial-peer voice command will start the H.323 processes, which causes the Cisco IOS device to process H.323 messages. To determine the Cisco IOS Software release that is running on a Cisco product, administrators can log in to the device and issue the show version command to display the system banner. The system banner confirms that the device is running Cisco IOS Software by displaying text similar to "Cisco Internetwork Operating System Software" or "Cisco IOS Software." The image name displays in parentheses, followed by "Version" and the Cisco IOS Software release name. Other Cisco devices do not have the show version command or may provide different output. The following example identifies a Cisco product that is running Cisco IOS Software Release 12.3(26) with an installed image name of C2500-IS-L: Router# show version Cisco Internetwork Operating System Software IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(26), RELEASE SOFTWARE (fc2) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2008 by cisco Systems, Inc. Compiled Mon 17-Mar-08 14:39 by dchih !--- output truncated The following example identifies a Cisco product that is running Cisco IOS Software Release 12.4(20)T with an installed image name of C1841-ADVENTERPRISEK9-M: Router# show version Cisco IOS Software, 1841 Software (C1841-ADVENTERPRISEK9-M), Version 12.4(20)T, RELEASE SOFTWARE (fc3) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2008 by Cisco Systems, Inc. Compiled Thu 10-Jul-08 20:25 by prod_rel_team !--- output truncated Additional information about Cisco IOS Software release naming conventions is available in "White Paper: Cisco IOS Reference Guide" at the following link: http://www.cisco.com/web/about/security/intelligence/ios-ref.html Products Confirmed Not Vulnerable +-------------------------------- Cisco IOS XR Software is not affected by these vulnerabilities. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= H.323 is the International Telecommunication Union (ITU) standard for real-time multimedia communications and conferencing over packet-based (IP) networks. A subset of the H.323 standard is H.225.0, a standard that is used for call signaling protocols and media stream packetization over IP networks. The H.323 implementation in Cisco IOS Software contains two DoS vulnerabilities. An attacker can exploit these vulnerabilities remotely by sending crafted H.323 packets to an affected device that is running Cisco IOS Software. A TCP three-way handshake is required to exploit these vulnerabilities. These vulnerabilities are documented in Cisco Bug IDs CSCtc73759 ( registered customers only) and CSCtd33567 ( registered customers only) , and have been assigned Common Vulnerabilities and Exposures (CVE) IDs CVE-2010-2828 and CVE-2010-2829, respectively. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at http://intellishield.cisco.com/security/alertmanager/cvss CSCtc73759 - Device crashing upon receipt of specific traffic CVSS Base Score - 7.8 Access Vector Network Access Complexity Low Authentication None Confidentiality Impact None Integrity Impact None Availability Impact Complete CVSS Temporal Score - 6.4 Exploitability Functional Remediation Level Official Fix Report Confidence Confirmed CSCtd33567 - Traceback seen when receiving crafted H.323 packets CVSS Base Score - 7.8 Access Vector Network Access Complexity Low Authentication None Confidentiality Impact None Integrity Impact None Availability Impact Complete CVSS Temporal Score - 6.4 Exploitability Functional Remediation Level Official Fix Report Confidence Confirmed Impact ====== Successful exploitation of the vulnerabilities described in this advisory may cause the affected device to reload. Theses vulnerabilities could be exploited repeatedly to cause an extended DoS condition. Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the following Cisco IOS Software table corresponds to a Cisco IOS Software train. If a particular train is vulnerable, the earliest releases that contain the fix are listed in the First Fixed Release For This Advisory column. The First Fixed Release for All Advisories in the September 2010 Bundle Publication column lists the earliest possible releases that correct all the published vulnerabilities in the Cisco IOS Software Security Advisory bundled publication. Cisco recommends upgrading to the latest available release, where possible. +--------------------------------------------------------------------+ | Major | Availability of Repaired Releases | | Release | | |------------+-------------------------------------------------------| | Affected | | First Fixed Release for | | 12.0-Based | First Fixed Release for | All Advisories in the | | Releases | This Advisory | September 2010 Bundle | | | | Publication | |--------------------------------------------------------------------| | There are no affected 12.0-based releases | |--------------------------------------------------------------------| | Affected | | First Fixed Release for | | 12.1-Based | First Fixed Release for | All Advisories in the | | Releases | This Advisory | September 2010 Bundle | | | | Publication | |------------+---------------------------+---------------------------| | | | Vulnerable;

Workarounds =========== There are no workarounds to mitigate these vulnerabilities apart from disabling H.323 if the Cisco IOS device does not require it. Applying access lists on interfaces that should not accept H.323 traffic and placing firewalls in strategic locations may greatly reduce exposure until an upgrade can be performed. Cisco provides Solution Reference Network Design (SRND) guides to help design and deploy networking solutions, which can be found at http://www.cisco.com/go/srnd Voice Security best practices are covered in the Cisco Unified Communications SRND Based on Cisco Unified Communications Manager 6.x at http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/6x/security.html To disable all H.323 call processing, administrators can issue the call service stop forced command under the voice service voip mode, as shown in this example: voice service voip h323 call service stop forced Note: The call service stop forced command disables all H.323 call processing. Additional mitigations that can be deployed on Cisco devices within the network are available in the companion document "Cisco Applied Mitigation Bulletin: Identifying and Mitigating Exploitation of the Multiple Vulnerabilities in Cisco Voice Products", which is available at the following location: http://www.cisco.com/warp/public/707/cisco-amb-20100922-voice.shtml Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities.

Cisco Security Advisory: Cisco IOS Software Session Initiation Protocol Denial of Service Vulnerabilities
by Cisco Systems Product Security Incident Response Team 22 Sep '10

22 Sep '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Cisco IOS Software Session Initiation Protocol Denial of Service Vulnerabilities Advisory ID: cisco-sa-20100922-sip http://www.cisco.com/warp/public/707/cisco-sa-20100922-sip.shtml Revision 1.0 For Public Release 2010 September 22 1600 UTC (GMT) - --------------------------------------------------------------------- Summary ======= Multiple vulnerabilities exist in the Session Initiation Protocol (SIP) implementation in Cisco IOS^ Software that could allow an unauthenticated, remote attacker to cause a reload of an affected device when SIP operation is enabled. Cisco has released free software updates that address these vulnerabilities. There are no workarounds for devices that must run SIP; however, mitigations are available to limit exposure to the vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20100922-sip.shtml Note: The September 22, 2010, Cisco IOS Software Security Advisory bundled publication includes six Cisco Security Advisories. Five of the advisories address vulnerabilities in Cisco IOS Software, and one advisory addresses vulnerabilities in Cisco Unified Communications Manager. Each advisory lists the releases that correct the vulnerability or vulnerabilities detailed in the advisory. The table at the following URL lists releases that correct all Cisco IOS Software vulnerabilities that have been published on September 22, 2010, or earlier: http://www.cisco.com/warp/public/707/cisco-sa-20100922-bundle.shtml Individual publication links are in "Cisco Event Response: Semiannual Cisco IOS Software Security Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep10.html Cisco Unified Communications Manager (CUCM) is affected by the vulnerabilities described in this advisory. Two separate Cisco Security Advisories have been published to disclose the vulnerabilities that affect the Cisco Unified Communications Manager at the following locations: http://www.cisco.com/warp/public/707/cisco-sa-20090826-cucm.shtml http://www.cisco.com/warp/public/707/cisco-sa-20100922-cucm.shtml Affected Products ================= These vulnerabilities only affect devices running Cisco IOS Software with SIP voice services enabled. Vulnerable Products +------------------ Cisco devices are affected when they are running affected Cisco IOS Software versions that are configured to process SIP messages. Recent versions of Cisco IOS Software do not process SIP messages by default. Creating a dial peer by issuing the dial-peer voice command will start the SIP processes, causing the Cisco IOS device to process SIP messages. In addition, several features within Cisco Unified Communications Manager Express, such as ePhones, will also automatically start the SIP process when they are configured, causing the device to start processing SIP messages. An example of an affected configuration follows: dial-peer voice <Voice dial-peer tag> voip ... ! In addition to inspecting the Cisco IOS device configuration for a dial-peer command that causes the device to process SIP messages, administrators can also use the show processes | include SIP command to determine whether Cisco IOS Software is running the processes that handle SIP messages. In the following example, the presence of the processes CCSIP_UDP_SOCKET or CCSIP_TCP_SOCKET indicates that the Cisco IOS device will process SIP messages: Router# show processes | include SIP 149 Mwe 40F48254 4 1 400023108/24000 0 CCSIP_UDP_SOCKET 150 Mwe 40F48034 4 1 400023388/24000 0 CCSIP_TCP_SOCKET Note: Because there are several ways a device running Cisco IOS Software can start processing SIP messages, it is recommended that the show processes | include SIP command be used to determine whether the device is processing SIP messages instead of relying on the presence of specific configuration commands. Cisco Unified Border Element images are also affected by two of these vulnerabilities. Note: The Cisco Unified Border Element feature (previously known as the Cisco Multiservice IP-to-IP Gateway) is a special Cisco IOS Software image that runs on Cisco multiservice gateway platforms. It provides a network-to-network interface point for billing, security, call admission control, quality of service, and signaling interworking. To determine the Cisco IOS Software release that is running on a Cisco product, administrators can log in to the device and issue the show version command to display the system banner. The system banner confirms that the device is running Cisco IOS Software by displaying text similar to "Cisco Internetwork Operating System Software" or "Cisco IOS Software." The image name displays in parentheses, followed by "Version" and the Cisco IOS Software release name. Other Cisco devices do not have the show version command or may provide different output. The following example identifies a Cisco product that is running Cisco IOS Software Release 12.3(26) with an installed image name of C2500-IS-L: Router# show version Cisco Internetwork Operating System Software IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(26), RELEASE SOFTWARE (fc2) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2008 by cisco Systems, Inc. Compiled Mon 17-Mar-08 14:39 by dchih !--- output truncated The following example identifies a Cisco product that is running Cisco IOS Software Release 12.4(20)T with an installed image name of C1841-ADVENTERPRISEK9-M: Router# show version Cisco IOS Software, 1841 Software (C1841-ADVENTERPRISEK9-M), Version 12.4(20)T, RELEASE SOFTWARE (fc3) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2008 by Cisco Systems, Inc. Compiled Thu 10-Jul-08 20:25 by prod_rel_team !--- output truncated Additional information about Cisco IOS Software release naming conventions is available in "White Paper: Cisco IOS Reference Guide" at the following link: http://www.cisco.com/warp/public/620/1.html Note: CUCM is affected by the vulnerabilities described in this advisory. Two separate Cisco Security Advisories have been published to disclose the vulnerabilities that affect the Cisco Unified Communications Manager at the following locations: http://www.cisco.com/warp/public/707/cisco-sa-20090826-cucm.shtml http://www.cisco.com/warp/public/707/cisco-sa-20100922-cucm.shtml Products Confirmed Not Vulnerable +-------------------------------- The SIP Application Layer Gateway (ALG), which is used by the Cisco IOS NAT and firewall features of Cisco IOS Software, is not affected by these vulnerabilities. Cisco IOS XR Software is not affected by these vulnerabilities. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= SIP is a popular signaling protocol that is used to manage voice and video calls across IP networks such as the Internet. SIP is responsible for handling all aspects of call setup and termination. Voice and video are the most popular types of sessions that SIP handles, but the protocol has the flexibility to accommodate other applications that require call setup and termination. SIP call signaling can use UDP (port 5060), TCP (port 5060), or Transport Layer Security (TLS; TCP port 5061) as the underlying transport protocol. Three vulnerabilities exist in the SIP implementation in Cisco IOS Software that may allow a remote attacker to cause an affected device to reload. These vulnerabilities are triggered when the device running Cisco IOS Software processes crafted SIP messages. Note: In cases where SIP is running over TCP transport, a TCP three-way handshake is necessary to exploit these vulnerabilities. These vulnerabilities are addressed by Cisco bug IDs CSCta20040, CSCsz43987 and CSCtf72678, and have been assigned Common Vulnerabilities and Exposures (CVE) IDs CVE-2010-2835, CVE-2009-2051 and CVE-2010-2834, respectively. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at http://intellishield.cisco.com/security/alertmanager/cvss CSCta20040 - Device crashes when receiving crafted SIP message CVSS Base Score - 7.8 Access Vector Network Access Complexity Low Authentication None Confidentiality Impact None Integrity Impact None Availability Impact Complete CVSS Temporal Score - 6.4 Exploitability Functional Remediation Level Official Fix Report Confidence Confirmed CSCsz43987 - IOS coredump when sending crafted packets CVSS Base Score - 7.8 Access Vector Network Access Complexity Low Authentication None Confidentiality Impact None Integrity Impact None Availability Impact Complete CVSS Temporal Score - 6.4 Exploitability Functional Remediation Level Official Fix Report Confidence Confirmed CSCtf72678 - IOS Coredump Generated when sending crafted packets CVSS Base Score - 7.8 Access Vector Network Access Complexity Low Authentication None Confidentiality Impact None Integrity Impact None Availability Impact Complete CVSS Temporal Score - 6.4 Exploitability Functional Remediation Level Official Fix Report Confidence Confirmed Impact ====== Successful exploitation of the vulnerabilities in this advisory may result in a reload of the device. Repeated exploitation could result in a sustained denial of service condition. Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the following Cisco IOS Software table corresponds to a Cisco IOS Software train. If a particular train is vulnerable, the earliest releases that contain the fix are listed in the First Fixed Release For This Advisory column. The First Fixed Release for All Advisories in the September 2010 Bundle Publication column lists the earliest possible releases that correct all the published vulnerabilities in the Cisco IOS Software Security Advisory bundled publication. Cisco recommends upgrading to the latest available release, where possible. +-------------------------------------------------------------------+ | Major | Availability of Repaired Releases | | Release | | |------------+------------------------------------------------------| | Affected | | First Fixed Release for | | 12.0-Based | First Fixed Release for | All Advisories in the | | Releases | This Advisory | September 2010 Bundle | | | | Publication | |-------------------------------------------------------------------| | There are no affected 12.0-based releases | |-------------------------------------------------------------------| | Affected | | First Fixed Release for | | 12.1-Based | First Fixed Release for | All Advisories in the | | Releases | This Advisory | September 2010 Bundle | | | | Publication | |-------------------------------------------------------------------| | There are no affected 12.1-based releases | |-------------------------------------------------------------------| | Affected | | First Fixed Release for | | 12.2-Based | First Fixed Release for | All Advisories in the | | Releases | This Advisory | September 2010 Bundle | | | | Publication | |------------+--------------------------+---------------------------| | 12.2 | Not Vulnerable | Vulnerable;

Cisco IOS XR System Software +--------------------------- Cisco IOS XR Software is not affected by the vulnerabilities disclosed in the September 22, 2010, Cisco IOS Software Security Advisory bundled publication. Workarounds =========== If the affected Cisco IOS device requires SIP for VoIP services, SIP cannot be disabled, and no workarounds are available. Users are advised to apply mitigation techniques to help limit exposure to the vulnerabilities. Mitigation consists of allowing only legitimate devices to connect to affected devices. To increase effectiveness, the mitigation must be coupled with anti-spoofing measures on the network edge. This action is required because SIP can use UDP as the transport protocol. Additional mitigations that can be deployed on Cisco devices within the network are available in the companion document "Cisco Applied Mitigation Bulletin:Identifying and Mitigating Exploitation of the Multiple Vulnerabilities in Cisco Voice Products", which is available at the following location: http://www.cisco.com/warp/public/707/cisco-amb-20100922-voice.shtml Disabling SIP Listening Ports +---------------------------- For devices that do not require SIP to be enabled, the simplest and most effective workaround is to disable SIP processing on the device. Some versions of Cisco IOS Software allow administrators to disable SIP with the following commands: sip-ua no transport udp no transport tcp no transport tcp tls warning Warning: When applying this workaround to devices that are processing Media Gateway Control Protocol (MGCP) or H.323 calls, the device will not stop SIP processing while active calls are being processed. Under these circumstances, this workaround should be implemented during a maintenance window when active calls can be briefly stopped. The show udp connections, show tcp brief all, and show processes | include SIP commands can be used to confirm that the SIP UDP and TCP ports are closed after applying this workaround. Depending on the Cisco IOS Software version in use, the output from the show ip sockets command may still show the SIP ports open, but sending traffic to them will cause the SIP process to emit the following message: *Jun 2 11:36:47.691: sip_udp_sock_process_read: SIP UDP Listener is DISABLED Control Plane Policing +--------------------- For devices that need to offer SIP services, it is possible to use Control Plane Policing (CoPP) to block SIP traffic to the device from untrusted sources. Cisco IOS Releases 12.0S, 12.2SX, 12.2S, 12.3T, 12.4, and 12.4T support the CoPP feature. CoPP may be configured on a device to protect the management and control planes to minimize the risk and effectiveness of direct infrastructure attacks by explicitly permitting only authorized traffic sent to infrastructure devices in accordance with existing security policies and configurations. The following example can be adapted to specific network configurations: !-- The 192.168.1.0/24 network and the 172.16.1.1 host are trusted. !-- Everything else is not trusted. The following access list is used !-- to determine what traffic needs to be dropped by a control plane !-- policy (the CoPP feature.) If the access list matches (permit) !-- then traffic will be dropped and if the access list does not !-- match (deny) then traffic will be processed by the router. access-list 100 deny udp 192.168.1.0 0.0.0.255 any eq 5060 access-list 100 deny tcp 192.168.1.0 0.0.0.255 any eq 5060 access-list 100 deny tcp 192.168.1.0 0.0.0.255 any eq 5061 access-list 100 deny udp host 172.16.1.1 any eq 5060 access-list 100 deny tcp host 172.16.1.1 any eq 5060 access-list 100 deny tcp host 172.16.1.1 any eq 5061 access-list 100 permit udp any any eq 5060 access-list 100 permit tcp any any eq 5060 access-list 100 permit tcp any any eq 5061 !-- Permit (Police or Drop)/Deny (Allow) all other Layer3 and Layer4 !-- traffic in accordance with existing security policies and !-- configurations for traffic that is authorized to be sent !-- to infrastructure devices. !-- Create a Class-Map for traffic to be policed by !-- the CoPP feature. class-map match-all drop-sip-class match access-group 100 !-- Create a Policy-Map that will be applied to the !-- Control-Plane of the device. policy-map control-plane-policy class drop-sip-class drop !-- Apply the Policy-Map to the Control-Plane of the !-- device. control-plane service-policy input control-plane-policy Note: Because SIP can use UDP as a transport protocol, it is possible to easily spoof the IP address of the sender, which may defeat access control lists that permit communication to these ports from trusted IP addresses. In the above CoPP example, the access control entries (ACEs) that match the potential exploit packets with the "permit" action result in these packets being discarded by the policy-map "drop" function, while packets that match the "deny" action (not shown) are not affected by the policy-map drop function. Additional information on the configuration and use of the CoPP feature can be found at http://www.cisco.com/web/about/security/intelligence/coppwp_gs.html and http://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gtrtlimt.html Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities.

Cisco Security Advisory: Cisco IOS Software Internet Group Management Protocol Denial of Service Vulnerability
by Cisco Systems Product Security Incident Response Team 22 Sep '10

22 Sep '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Cisco IOS Software Internet Group Management Protocol Denial of Service Vulnerability Advisory ID: cisco-sa-20100922-igmp http://www.cisco.com/warp/public/707/cisco-sa-20100922-igmp.shtml Revision 1.0 For Public Release 2010 September 22 1600 UTC (GMT) - --------------------------------------------------------------------- Summary ======= A vulnerability in the Internet Group Management Protocol (IGMP) version 3 implementation of Cisco IOS Software and Cisco IOS XE Software allows a remote unauthenticated attacker to cause a reload of an affected device. Repeated attempts to exploit this vulnerability could result in a sustained denial of service (DoS) condition. Cisco has released free software updates that address this vulnerability. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20100922-igmp.shtml Note: The September 22, 2010, Cisco IOS Software Security Advisory bundled publication includes six Cisco Security Advisories. Five of the advisories address vulnerabilities in Cisco IOS Software, and one advisory addresses vulnerabilities in Cisco Unified Communications Manager. Each advisory lists the releases that correct the vulnerability or vulnerabilities detailed in the advisory. The table at the following URL lists releases that correct all Cisco IOS Software vulnerabilities that have been published on September 22, 2010, or earlier: http://www.cisco.com/warp/public/707/cisco-sa-20100922-bundle.shtml Individual publication links are in "Cisco Event Response: Semiannual Cisco IOS Software Security Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep10.html Affected Products ================= Vulnerable Products +------------------ The following products are affected by this vulnerability: * Cisco IOS Software * Cisco IOS XE Software To determine the Cisco IOS Software release that is running on a Cisco product, administrators can log in to the device and issue the show version command to display the system banner. The system banner confirms that the device is running Cisco IOS Software by displaying text similar to "Cisco Internetwork Operating System Software" or "Cisco IOS Software." The image name displays in parentheses, followed by "Version" and the Cisco IOS Software release name. Other Cisco devices do not have the show version command or may provide different output. The following example identifies a Cisco product that is running Cisco IOS Software Release 12.4(20)T with an installed image name of C1841-ADVENTERPRISEK9-M: Router#show version Cisco IOS Software, 1841 Software (C1841-ADVENTERPRISEK9-M), Version 12.4(20)T, RELEASE SOFTWARE (fc3) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2008 by Cisco Systems, Inc. Compiled Thu 10-Jul-08 20:25 by prod_rel_team Additional information about Cisco IOS Software release naming conventions is available in White Paper: Cisco IOS and NX-OS Software Reference Guide. Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by this vulnerability. Cisco IOS XR Software is not affected by this vulnerability. The IGMP version 1, IGMP version 2, and IPv6 Multicast Listener Discovery protocol (MLD) features in Cisco IOS and Cisco IOS XE Software are not affected by this vulnerability. Details ======= Internet Group Management Protocol (IGMP) is the protocol used by hosts and adjacent routers to manage membership in IP multicast groups. The IGMP version 3 protocol permits source-specific multicast which allows hosts to specify the IP address of the multicast source. A malformed IGMP packet can cause a vulnerable device to reload. This vulnerability can only be exploited if the malformed IGMP packet is received on an interface that has been enabled for IGMP version 3 and Protocol Independent Multicast (PIM). The malformed IGMP packet destination address can be unicast, multicast, or broadcast and can be addressed to any IP address in the vulnerable device, including loopback addresses. To exploit this vulnerability, a malformed packet must be received on a vulnerable interface, but it can be addressed to any IP address on the vulnerable device. Transit traffic will not trigger this vulnerability. A vulnerable interface configuration requires the PIM mode of operation (sparse-dense, sparse, or dense) to be configured in addition to the ip igmp version 3 command. The three possible configurations that permit exploitation of this vulnerability are: !--- Interface configured for PIM sparse and IGMPv3 interface GigabitEthernet0/0 ip address 192.168.0.1 255.255.255.0 ip pim sparse-mode ip igmp version 3 !--- Interface configured for PIM sparse-dense and IGMPv3 interface GigabitEthernet0/1 ip address 192.168.1.1 255.255.255.0 ip pim sparse-dense-mode ip igmp version 3 !--- Interface configured for PIM dense and IGMPv3 interface GigabitEthernet0/2 ip address 192.168.2.1 255.255.255.0 ip pim dense-mode ip igmp version 3 The IGMP version 3 lite feature is unrelated to this vulnerability, in that the presence or absence of the ip igmp v3lite command on an interface does not change the vulnerable condition of that interface. The IP router alert option may or may not be present in packets attempting to exploit the vulnerability described in this document. This vulnerability is documented in Cisco bug ID CSCte14603 ( registered customers only) . This vulnerability has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2010-2830. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerability in this advisory based on the Common Vulnerability Scoring System (CVSS).

Workarounds =========== Additional mitigations that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory, which is available at the following link: http://www.cisco.com/warp/public/707/cisco-amb-20100922-igmp.shtml IGMP version 2 +------------- Customers who do not require the Source Specific Multicast (SSM) functionality can use IGMP version 2 as a workaround. interface GigabitEthernet0/0 ip address 192.168.0.1 255.255.255.0 ip pim sparse-mode ip igmp version 2 Control Plane Policing +--------------------- A partial mitigation of the vulnerability described in this document is to block IGMP packets with an IP Time to Live (TTL) field value that is not equal to 1. RFC1054 leavingcisco.com, "Host Extensions for IP Multicasting" RFC2236 leavingcisco.com, "Internet Group Management Protocol Version 2", and RFC3376 leavingcisco.com, "Internet Group Management Protocol Version 3", indicate that every IGMP message is sent with an IP TTL of 1. CoPP may be configured on a device to protect the management and control planes, and minimize the risk and effectiveness of direct infrastructure attacks by explicitly permitting only authorized traffic sent to infrastructure devices in accordance with existing security policies and configurations. The following example can be adapted to your network. Drop of IGMP packets with unicast IP destination addresses can also be implemented with CoPP if the network is using all multicast applications that utilize only multicast group destination addresses for IGMP packets. ! !-- The following access list is used !-- to determine what traffic needs to be dropped by a control plane !-- policy (the CoPP feature.) If the access list matches (permit), !-- then traffic will be dropped. If the access list does not !-- match (deny), then traffic will be processed by the router. !-- all IGMP packets with ttl different from 1 will be selected !-- by this acl and the "drop" action will be applied in the !-- corresponding CoPP polisy ! ip access-list extended IGMP-ACL permit igmp any any ttl neq 1 ! !-- Permit (Police or Drop)/Deny (Allow) all other Layer3 and Layer4 !-- traffic in accordance with existing security policies and !-- configurations for traffic that is authorized to be sent !-- to infrastructure devices. !-- Create a class map for traffic that will be policed by !-- the CoPP feature. ! class-map match-all drop-IGMP-class match access-group name IGMP-ACL ! !-- Create a policy map that will be applied to the !-- Control Plane of the device, and add the "drop-tcp-traffic" !-- class map. ! policy-map CoPP-policy class drop-IGMP-class drop ! !-- Apply the policy map to the control plane of the !-- device. ! control-plane service-policy input CoPP-policy Additional information on the configuration and use of the CoPP feature is available in the Control Plane Policing Implementation Best Practices.

RE: IPv6 tunnel brokers that provide BGP other than HE?

We do the same with HE, but we announce a /32 we have from arin. I think most of our upstreams do native ipv6 I'm just to lazy to flip the switches. Considering were not really giving ipv6 to customers yet(soon). Even when we go native, I figure we'll keep a session with HE, Don't see any disadvantages of it..

IPv6 tunnel brokers that provide BGP other than HE?
by Matthew Huff 22 Sep '10

22 Sep '10

Neither of our upstream providers offer direct ipv6 although both claim deployment in Q1 2011. In the meantime, we have a tunnel with BGP to HE announcing our /48, but we are looking for redundancy. Is there anyone else out there offering services like Hurricane Electric? ---- Matthew Huff | One Manhattanville Rd OTA Management LLC | Purchase, NY 10577 http://www.ox.com | Phone: 914-460-4039 aim: matthewbhuff | Fax: 914-460-4139
