Call for Nominations to the NANOG Programme Committee
by Joe Abley 24 Sep '07

24 Sep '07

The NANOG PC is a group of sixteen individuals from the NANOG community who together are responsible for the solicitation and selection of material for NANOG meeting programmes. A new NANOG Programme Committee will be selected by the NANOG Steering Committee after the SC election in October. Eight positions are to be filled, and the SC is now seeking nominations. http://www.nanog.org/pccandidates07.html Per the NANOG charter (6.2.1), eligible candidates are individuals who have attended at least one NANOG meeting in the past 12 months (i.e. one or more of NANOG 39, NANOG 40 or NANOG 41). Broad technical knowledge of Internet operations and familiarity with NANOG meetings are useful attributes. Having constructive opinions and ideas about how NANOG meetings might be improved is of high value. If you are interested in nominating someone else or yourself, please send a brief note to steering(a)nanog.org. The note should include the nominee's contact details, and a brief description of why (in your opinion) the individual concerned would be a good addition to the PC. The SC will accept nominations received before the end of NANOG 41 on October 16. Joe (for the NANOG SC)

Apple Airport Extreme IPv6 problems?
by Barrett Lyon 24 Sep '07

24 Sep '07

Apple is nice enough to provide an automatic v6 tunnel from their new Airport Extreme units. They even get all the machines on the network to participate -- by default! At first this did not seem to be much of an issue, it was even pretty cool. However, I noticed as I roll out more v6 services to support native v6 users, I am impacting the network performance of almost all of the Apple airport population that has an inefficient tunnel configuration. The user obviously will take the AAAA v6 published IP over the v4 A record. Don't get me wrong v6 tunnels are great, when you opt-in and know what you are getting into. For example, my grandparents tunnel in California goes to Virginia. This impacts the user experience rather significantly with the first hop being nearly 100ms where their services to California are ~20ms. It's painful for a lot of users, especially when they don't even know what's going on. Has anyone else ran into this? It's not pretty for a CDN or anyone trying to provide a quality service over v6, shunting users over inefficiently tunneled routes does not sit well with me. I think Apple has made a mistake by enabling this by default. -Barrett

IPv6 Availability Manager Data Sheet
by Henry Linneweh 24 Sep '07

24 Sep '07

Having followed for many months on ipv6 deployments. I noticed a lacking of management sofrware from any major venders mentioned. So I am contributing to what I hope will bring some of these tools to the forfront http://www.software.emc.com/collateral/content_management/S0086-smarts-ipv6… -Henry

Route table growth and hardware limits...talk to the filter
by Jon Lewis 23 Sep '07

23 Sep '07

This evolved from a thread on another list. I think it's more appropriate for nanog, so here it is. Since many of you probably aren't on the other list, some context is lost, but it shouldn't matter. The prefix-list presented below should be considered a proof-of-concept / work-in-progress. As stated below, no testing has been done to verfiy it will cause no loss in connectivity (i.e. due to networks deaggregating their space and announcing it only as longer subnets than their RIR states are the minimum allocation size for the range from which their CIDRs were carved). OTOH, this _should_ be a relatively safe way for networks under the gun to upgrade (especially those running 7600/6500 gear with anything less than Sup720-3bxl) to survive on an internet with >~240k routes and get by with these filtered routes, either buying more time to get upgrades done or putting off upgrades for perhaps a considerable time. Here's what I ended up with (so far) based on Barry Greene's work at ftp://ftp-eng.cisco.com/cons/isp/security/Ingress-Prefix-Filter-Templates/ T-ip-prefix-filter-ingress-strict-check-v18.txt While working on this, I noticed a bunch of inconsistencies in the expected RIR minimum allocations in ISP-Ingress-In-Strict and in the data actually published by the various RIRs. I've adjusted the appropriate entries, and as previously mentioned, flipped things around so that for each of the known RIR /8 or shorter prefixes, prefixes longer than RIR specified minimums (or /24 in cases where the RIR specifies longer than /24) are denied. Due to the number of minimum acceptable allocation inconsistencies, I recollected all the data on number of routes shaved per RIR filter. For some reason, today I started out with fewer routes (228289...yesterday, I started with 230686) with no filtering. RIR filter section Reduction in routes APNIC 16690 ARIN 41070 RIPE 16981 LANIC 4468 AFRINIC 1516 ----------------------------- TOTAL 80725 The end result of applying all the RIR minimum allocation filters was 147564 BGP routes. I haven't checked to make sure there was no loss in reachability...this is just an idle 7206/NPE225 with nothing but its ethernet uplink. The prefix-list I'm using for this experiment is: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!
