  1. BGP convergence in much less than a second

    Martin Winter, Cisco


    This presentation discussed a new technology, which allows BGP convergence in less than a second. The technology is known as BGP PIC - Prefix Independent Convergence.
    The key technology described in the presentation was hierarchical FIB. The presentation examined use of the technology in two scenarios: the core scenario and the H scenario.

    Questions and discussion

    • It was noted that this technology applies to CSR routers, and it was asked if there were plans to also apply it to 7500 and 6500 series.
      The presenter responded that due to support issues it would most likely be for IOX onwards.
      The presenter later added that the situation for the 7600 series was looking promising.
    • Speakers were reminded to state their name before speaking.
    • The presenter mentioned his presentation had changed and the version on the web site was not current.
      The Chair noted that all updated presentations had been sent to APNIC, and would hopefully be uploaded in the evening.

  2. BGP aggregation and de-aggregation report

    Philip Smith, Cisco

    This presentation discussed aggregation recommendations for ISPs produced by the RIPE Routing Working Group. The recommendations were published as RIPE-399. The presenter discussed the history of aggregation, causes of de-aggregation, the impact on global routing system, and some available solutions and recommendations for ISPs.

    Questions and discussion

    • It was asked what criteria were used - aggregation, common path attributes, no holes? The presenter agreed it would be what you would normally expect.
    • There was a comment that it was suspected that ISP aggregation problems were caused by not using NOEXPORT on /24s. It was asked if the majority of these ISPs were using STM1s or STM4s.
    • There was a comment that the global Internet should not have to pay for traffic engineering.
    • There was a comment that in many regions de-aggregation was caused by a lack of communication as well as knowledge, whereas in North America and issues of diversity and resilency were to blame.
    • It was suggested that tools are available to do this. However, it was argued that most people were concerned with how their network ran rather than how everyone else's ran. Therefore there was no incentive, and, of course, some people did not know how to do it.
    • It was noted that proxy aggregation was something that did not need to be done, and was not done, because of NOEXXPORT. It was noted that the American military were the only people who did it, and it was not advisable to emulate them.

  3. Deployment of 32 bit ASNs

    Andrei Robachevsky, RIPE NCC

    This presentation discussed RIPE NCC's experience of implementing the 32 bit ASN policy and deploying 32 bit ASNs.

    Questions and discussion

    • It was asked how many 'person years' went into implementing 32 bit ASNs.
      Concern was expressed regarding the amount of money that went into this process at RIPE.
    • It was noted that APNIC were able to use a lot of RIPE's work, but the implementation process still took longer than expected.
    • It was suggested that notation did not matter, even thought it had caused a lot of stress.
      It was suggested that in practice, Quagga would work.

  5. Co-chair election

    Philip Smith, Cisco

    The Chair noted that Randy Bush had volunteered to resign as co-chair, and it had been decided to elect two co-chairs because of the size and popularity of the routing SIG. The two nominees were Randy Bush and Tomoya Yoshida. They were therefore elected unopposed.

    Questions and discussion

    • Randy Bush noted that in other SIGs the Chair sometimes had to do all of the work. It was suggested that this had previously happened in the routing SIG, and he called for volunteers to assist in an unofficial capacity.
    • The Chair thanked Randy for his valuable support and welcomed Tomoya Yoshida. Tomoya Yoshida was asked to stand.
