Bonica 17:50-18:05 Inter AS option for BGP/MPLS IP VPN - M. Halstead draft-kulmala-l3vpn-interas-option-d-02 18:05-18:20 Reqs for MPLS Services Over L3VPN - K. Kumaki draft-kumaki-l3vpn-e2e-rsvp-te-reqts-00 18:20-18:35 Multicast Requirements - T. Morin draft-ietf-l3vpn-ppvpn-mcast-reqts-05 18:50-19:35 Multicast Solutions - E. Rosen, R. Aggarwal draft-ietf-l3vpn-2547bis-mcast-01 draft-raggarwa-l3vpn-2547bis-mcast-bgp-01 19:35-19:50 Multicast Experience - Y. Cai draft-ycai-mvpn-experience-00.txt Alex Zinin asked for a change in the Agenda - try to fit Sam Hartman in for a security issues overview sometime during the first hour. One of the presenters will be unable to attend. Sam can talk during the slot assigned to that individual. Working Group Status - R. Bonica Ross Callon announced that he would be resigning at working group chair effective the end of the IETF week for two reasons: In order to free up more time for his new IESG role, and because he feels that the group has two other very good co-chairs who can do well in his absence. Available at http://tools.ietf.org/wg/l3vpn: Inter AS option for BGP/MPLS IP VPN - M. Halstead - draft-kulmala-l3vpn-interas-option-d-02 See presentation. Should we adopt this as a working group document. Ron Bonica asked a question about slide 3 - is there a mapping function at the ASBR for adapting RT/RD in one AS to RT/RD in another. Not a mapping so much as a replacement, the upshot is that there is no requirement to coordinate between one AS and another. Ron then asked a question about slide 4 - ??? Something about service providers not wanting to share a view od their internal VPN with another service provider. Yakov Rehkter asked a question about slide 3 - ??? Load balancing issues drive use of unique RDs at the ASBR. Ron Bonica asked for a show of hands for people who read the draft? A few. Ron then asked for a show of hands for operators in the room? Not many. Ron asked for hands of those in favor of adopting? A few. Ron then asked for hands those against adopting? None. Take it to the list... =============================================================== Mark Townsley talked about work he and Sam Hartman did on l3vpn security issues. Sam has gone through all the documents and understands the VPN technology. There are issues that are "sticking" the MPLS/GRE and L2TP(?) Mark then said that he had completed his update and turned the meeting back over to the WG. =============================================================== Multicast Requirements - T. Morin - draft-ietf-l3vpn-ppvpn-mcast-reqts-05 Mr Morin was not in. Ron started to show his slides, but then said they were available. The draft will be going to last call as soon as possible after the meeting. There was a discussion (rat-hole) on RFC 1264 issues and the fact that this document includes some IPv6 "stuff" that has not been implemented. =============================================================== Christian Jaquinet gave a presentation on draft-halstead-guichard-mavs-requirements-01.txt See slides. =============================================================== 18:50-19:35 Multicast Solutions - E. Rosen, R. Aggarwal draft-ietf-l3vpn-2547bis-mcast-01 draft-raggarwa-l3vpn-2547bis-mcast-bgp-01 See presentation. Eric Rosen summarized the current status of the work on these drafts. R. Aggarwal continued presentation on inter-AS MVPN specific details. Eric Rosen continued with a few topical discussion points, a mention of things they yet need to do and a wrap up. Dave Thaler - what is the impact of dampening the joins and not the prunes (or vice versa) Ron Bonica (individual) - raised a concern about the permutations of the various options and asked if there were some combinations that don't make sense in any application. So, would it make some sense to provide application examples for each combination? Eric said that this should be in a different document because it will add more issues to generate disagreement. Luyuan Fong - asked what the difference is in the multi-homing case between unicast and multicast? Also, how will a customer set the options they us in the multi-AS. Eric Rosen said that we have so many options now because people asked for them. Yakov Rekhter said that not everyone is going to make the same choices, consequently, there are different options. Ron said that all this is true, but - at some point we will have to decide which of the various options/combinations will get fleshed out. Yakov said that we could define a "must implement" subset and still not dictate what different implementations actually do. Mark Townsley said that would make his job easier. =============================================================== 19:35-19:50 Multicast Experience - Y. Cai draft-ycai-mvpn-experience-00.txt Yiqun Cai gave a presentation on this draft. See slides.
