96.0.0.0/6 reachability testing

Randy's MUA automatically deletes email sent directly to him...can anyone else here provide some insight into the reachability testing provided for this allocation given to Randy from ARIN? Thanks, -ron ------ Forwarded Message From: "da Silva, Ronald" <ronald.dasilva(a)twcable.com> Date: Mon, 30 Apr 2007 12:14:52 -0400 To: <randy(a)psg.com> Conversation: 96.0.0.0/6 reachability testing Subject: 96.0.0.0/6 reachability testing Randy - I see...96.0.0.0/16 flagged for reachability testing, but we have allocations from 98.0.0.0/8 and seem to be educating folks like <omitted> and others to drop stale bogon filters...you see any issues with the 96/16 block? If not, it might be a false positive for the rest of the /6...perhaps folk were applying policies based on /8's instead of the /6...

Re: BGP Session Timeout

Depending on your hardware, you can trigger your BGP and IGP to shut sessions when the peer is gone. On some cisco, you can have BFD (Bidirectional Forwarding Detection). you have to enable this on both sides. If BFD notices the peer is down, it will notify OSPF,BGP,... (if configured so). for example: ! interface GigabitEthernet0/0 ip address 10.1.1.1 255.255.255.252 bfd neighbor 10.1.1.2 bfd interval 250 min_rx 250 multiplier 3 ip ospf bfd ! This will send a BFD packet every 250ms, expect one every 250ms and if 3 packets are missed (after 750ms) it will tell OSPF to shut any session towards 10.1.1.2 (or routed via 10.1.1.2 for the BGP case).

BGP Session Timeout
by Saqib Ilyas 01 May '07

01 May '07

I have a question regarding BGP session time outs. Is it likely that BGP times out before underlying IP topology reconvergences after a link/node failure? Do service providers ever set such low values of BGP timeouts that BGP timeout will occur? If not, what else may cause a BGP session to time out? -- Muhammad Saqib Ilyas PhD Student, Computer Science and Engineering Lahore University of Management Sciences

Hello- This announcement is being sent to multiple lists. Apologies for any duplicates. ARIN was issued the IPv4 address blocks 96/8, 97/8, 98/8, and 99/8 by the IANA on Oct. 3, 2006. ARIN is now issuing /20 and shorter prefixes from these blocks to customers. Network operators may wish to adjust any filters in place accordingly. For informational purposes, a list of ARIN's currently administered IP blocks can be found at: http://www.arin.net/reference/ip_blocks.html Regards, Leslie Nobile Director, Registration Services American Registry for Internet Numbers (ARIN)

from the academic side of the house

For the first set of IPv6 records, a team from the University of Tokyo, WIDE Project, NTT Communications, JGN2, SURFnet, CANARIE, Pacific Northwest Gigapop and other institutions collaborated to create a network path over 30,000 kilometers in distance, crossing 6 international networks - over 3/4 the circumference of the Earth. In doing so, the team successfully transferred data in the single and multi-stream categories at a rate of 7.67 Gbps which is equal to 230,100 terabit-meters per second (Tb-m/s). This record setting attempt leveraged standard TCP to achieve the new mark. The next day, the team used a modified version of TCP to achieve an even greater record. Using the same 30,000 km path, the network was able to achieve a throughput of 9.08 Gbps which is equal to 272,400 Tb-m/s for both the IPv6 multi and single stream categories. In doing so, the team surpassed the current IPv4 records, proving that IPv6 networks are able to provide the same, if not better, performance as IPv4. --bill
