cisco 9.1(7) BGP will lose local routes when also redistributed via IGRP
by pushp＠CERF.NET 06 Oct '93

06 Oct '93

In the following configuration: router bgp 1740 network 134.24.0.0 network 128.48.0.0 redistribute igrp 195 neighbor etc .. The cisco 9.1(7) code loses the 134.24 route and stops annoucing it to peers, if igrp 195 is also supplying it. If you recently upgraded to 9.1(7) and depending on how you like to configure your bgp, the one or two networks that you may have listed explicitly using the "network x " subcommand (maybe your backbone or DMZ nets) may not currently be reachable from outside .. The workaround is to remove the "network x " command --pushpendra Pushpendra Mohta pushp(a)cerf.net +1 619 455 3908 CERFNet

Re: the NIC?
by henryc＠oar.net 06 Oct '93

>Have you requested a block and had trouble? Scott, Well, ummm, yeah. We recently asked for a 256 address block of Class C space and was told to go to ANS for addresses. We've currently got a 256 block that's about used up, plus we obtained another 256 block for a customer of ours who had burned their B. We were asked to prove that we had used up both blocks (and proving that we had) were then told to go to ANS. I can put in arguments here about supernetting, routing, and multihomed networks. It doesn't make sense to me for a network that is multihomed to have a portion of someone else's address space... We'd thought about just asking for a 1024 address block, but given our recent experiences (we really got grilled on the second 256 block ["are you using those numbers"]), we decided not to even try. henry

PRDB Minutes from Regional-Techs Meeting in Ann Arbor
by Dale S. Johnson 05 Oct '93

05 Oct '93

These are notes from Monday's presentation at the Regional-Techs meeting in Ann Arbor. Merit will be compiling some kind of results from the meeting, but I'm about to be out on vacation for a couple of weeks and I'd like to get these to Regional-Techs before I leave. Apologies for the separate mailing. --Dale Status of Merit PRDB support of CIDR (and other assorted enhancements): --------- PRDB Support for CIDR: "CIDR-1" (The ability to accept and propogate aggregates): Finished; ready for testing & deployment when GateD is ready. (Includes NACR and auto-NACR updates, gated generation, reports, whois support). Input: Identical to old NACR, except that "x.x.x/len" is now supported where "x.x.x" used to be supported. The old format will still work: if the length is left off, this will be assumed to be a Class A, B, or C as appropriate. Output: In all published output, "x.x.x" is replaced by "x.x.x/len" . (Exception: nets.unl.now has the fields separately. The Right Thing is done within the GateD configuration files). "CIDR-2" (The ability for NSFNET to create aggregates on behalf of its peers): Targeted for mid-November, to be ready for BGP-4 in GateD. Input: Identical to the old NACR, with the addition of zero or more lines labelled "trigger"* following "netname": netnum: 193/8 [exact] netname: All_of_Europe trigger: 193.0.0/24 exact trigger: 193.1/16 refines If trigger lines are present, then the "netnum" line may contain an optional keywork "refines" or "exact" to modify the way this aggregate is exported from AS-690. The contents of the "trigger" line may be any classless IP address ("x.x.x/len") which is fully contained within netnum, followed by at most one of the words "refines" or "exact". Output: Aggregates created this way will be included with all other nets in all current reports of nets (whois and published files). All aggregates created this way will be automatically entered into the Aggregate Registry. This database will be searchable by whois, reports will be published (ftp, gopher), and an "exchange format" of the entire contents of the registry will be published. (See Aggregate Registry discussion later). A separate report of AS 690 Created Nets with their triggers and full definitions (flags) will be produced. --------- Other PRDB enhancements: Whois Server: All the functionality of the "dbshow" clients is now available via "whois -h prdb.merit.edu". "Whois help" for help. Nets reports: "nets.unl.now" ("unload" format) and "nets.tag.now" ("tagged format") are now published containing all information about nets. Home AS: Very soon accepted in NACRs, and published in nets reports. This inspired a lively discussion about how the community can encourage each other to fill in this information, since it is not required for NSFNET routing, and since we have about 13000 current networks registered without this information. But the PRDB software is ready and willing to be used. US State: Accepted in NACRs, and published in nets reports and in a new nets.by.state report. policy.as_690: Modified/expanded RIPE format of AS 690 AS policy, published for automatic updating of RIPE database. Shared Whois project: negotiations currently underway to modify our Organization Address fields to be compatible with the NIC, RIPE, and others. Then, to compare and update each others' data. (See SWIP presentation). CLNP Support: We have a preliminary schema and some initial forms and report formats for supporting CLNP in the PRDB. Nodes and Applications (with their addresses), RDIs, and contacts are included. Gated will be generated; information will be available via whois, ftp, and gopher. Motif Support: We are looking for ways to speed development, and are experimenting with a Motif GUI builder. Is there an X-based application that would be most useful to you that we should experiment on first? (Anyone want to trade notes on GUI builders?) --------- Aggregate Registry Development (Non-NSFNET Specific): We spent quite a bit of time on this; details to follow. The "Aggregate Registry" concept of RFC 1482 will be split into an AS-based "Routing Registry" and a separate "Routed Net Registry", which will include not only Aggregates but also any other "Classless Net" that needs registration. (Possibly every net on the connected Internet?). All such nets will be entered only by their Home AS or their creators (in the case of aggregates); not by everyone who announces them. If other organizations build similar registries, this one will exchange information with them on a peer basis or otherwise simulate a full distributed database solution. -------- Upcoming non-backward-compatible changes: It is likely that the format of the Organization Address field in the new nets.unl.now and nets.tag.now reports may change as a result of the SWIP ("Shared Whois") project reconciling Organization Address schemas between Merit, the InterNic, RIPE, and others. Merit's single field will lilely be broken into multiple independent subfields within the current single field. The format of all AS 690 announcement lists in all PRDB input and output everywhere *might* have to change as a result of supporting multiple gateways to single ASs. (E.g. a syntax something like: 1:200(NSS1) 2:200(NSS2) ). Then again, maybe not. Your opinions on ways to minimize disruption in the reports are welcome. Many Net reports are scheduled to go away Nov 1. See the file nic.merit.edu:nsfnet/announced.networks/reports.summary for details.

Interested in what current projects are underway to develop new Internet documentation and tools? Wondering if there are other groups who would like to collaborate on projects you'd like to see completed? Want to know what's just around the corner in the way of networked information and services? Then attend NIC Fest '93 and have all of these questions answered by leading Internet experts. Meet your colleagues from around the country and discuss common issues while getting to know the person attached to the email addresses you know so well. Join us for a day-long workshop specifically designed for network information center (NIC) management, staff, and anyone responsible for supporting Internet users. In addition to a day full of useful information and interaction, you'll receive a free copy of the first issue of NICLink, a CD-ROM based collection of Internet reference materials. (see below) NIC Fest '93, sponsored by InterNIC Information Services will be held on Saturday, November 6, 1993 in San Diego, California. NIC Fest '93 is being held in conjunction with the ACM SIGUCCS '93 conference by invitation of the SIGUCCS Networking Task Force. The SIGUCCS conference is being held in San Diego on November 7-10. For more information on the ACM SIGUCCS conference, FTP to ftp.csus.edu or send mail to siguccs(a)csus.edu. NIC Fest will offer interactive tutorials and discussions on topics of immediate relevance to NIC personnel. Our goal is to leave you informed and up-to-date on NIC tools, projects, and futures. Instructors include leading NIC staffers from around the Internet, representing InterNIC Information Services, Directory and Database Services, Registration Services, the Clearinghouse for Networked Information Discovery and Retrieval (CNIDR), the IETF User Services Working Group, and Bunyip Information Systems. Sessions, all plenary: * The InterNIC - what it is and what it can do for you. A major goal of the InterNIC is to provide services for midlevel and campus NICs. Therefore the first session of the day will be two- way exchange between the InterNIC and attendees to discuss current and future InterNIC projects. Input to the InterNIC staff will be encouraged during this session and throughout the workshop. Moderators: Susan Calcari, Subu Subramanian, and Scott Williamson. * Network Tools - The latest methods for information retrieval, organization, and display, how they work. Gopher, freeWAIS, Archie, Whois++: integration issues and pros and cons discussed from the service provider's perspective. Current status and near future (6 months) developments on all your favorite tools. Instructor: Jane Smith of the Clearinghouse for Network Information Discovery and Retrieval (CNIDR). * NIC Projects BOF - IETF Working Groups. Designed as a "Birds of a Feather", a meeting where everyone with ideas about a given topic gathers to discuss their ideas, interact, learn from each other, and move new projects forward. This first BOF will discuss projects underway in the IETF User Services Working Groups to improve the use and management of networked information. The IETF (Internet Engineering Task Force) Working Groups are a major force in international cooperation to produce documents very useful to end users and network information centers, such as the FYI series of RFC's. BOF Leader: Joyce Reynolds, IETF Area Director, User Services * NIC Projects BOF - Europe and Asia-Pacific. A continuation of NIC Projects discussions with an emphasis on European organizations such as EARN, RIPE, and the RIPE NCC. A new network information center being established to serve the Asia-Pacific community will also be discussed. BOF Leader: Joyce Reynolds * NIC Fest Forum. Attendee participation and two-way communications will be encouraged throughout NIC Fest. However at the end of the day an open forum will be held to give attendees an opportunity to describe their own projects, and for continued discussions of the days topics. Beliefs, convictions, and opinions will be especially welcome during this session. * Upcoming Developments in Cyberspace. Future (1 year) developments in the world of networked information. Will include eye-witness account of the Frankfurt Book Fair, largest book publisher's meeting in the world.

BGP problem 'lost middleman'
by aggarwal＠nisc.jvnc.net 04 Oct '93

Dunno if this has happened to others before, but in case not: I have a setup where 3 routers (ciscos, running 9.1.x if that's important) are running IBGP. A---------B-----------C | ext-net Router-A peers with 'B' & 'C', Router-B peers with B & C and C with B&A (a full IBGP mesh). Router A is an exit/border router. In addition to BGP, the routers run IGRP. The BGP routes are kept separate from the IGRP routes. For whatever reason (not a configuration error), the BGP session between A-B died but not between A-C, B-C. The result was that C 'knew' via the BGP session with A, that to get to external network 'ext-net', it should send traffic to A. It does the IGRP lookup to get to A, and sends the traffic to 'B'. However, since B did not have a BGP session with A, it did not know how to get to the ext-net (in the real case, B was sending traffic back to C since the default route was via C). A potential disaster!! I realize that the problem was the unexpected 'lost' BGP session between A-B, but are we sure that in a more complicated topology, something similar cannot happen ? What really make me worried is that there doesn't seem to be way to detect this kind of a problem easily.. how do others monitor their BGP sessions ? -vikas vikas(a)jvnc.net

In general the idea is good. Within Ripe a new working group called the "EEPG" was started at the last Ripe meeting, and this group has a very simular agenda. Chairman is Bernhard Stockman. To Peter F's proposal I have a comment; > Interexchange coordination (e.g. Mae-East, etc.) > (network operators as customers of NSFNET NAPs) As the 'GIX-part' of MAE-east servers the Universe, not only one part of the global Internet, I would stress that is one of the tasks of the IEPG, if we all agree on that the IEPG is the place where the regional coordinating bodys meet. As the US side has NAP's and Europe has IXF's, and they are different, It makes sence to put them on the regional agenda. -Peter > cheers and see you in A**2, This message is brought to you from Holiday Inn, AA... -Peter (L)
