Notes taken by Stewart Bryant and Mike Horn, consolidated by Mark Townsley. Intro - no comments from floor draft-ietf-l2tpext-sesinfo-04.txt plan to issue last call Ron da Silva L2TP Active Discovery Few changes Editorial update then request last call No response from floor M. Townsley - L2TP Extension for Frame Relay PW Reviewed initial draft v00, requested feedback on the mailing list. Comments: Discussions focused on fragmentation issues Andy Malis - use FRF-12 in FR endpoint George Wilkie - Fragmantation - best to do it on end systems, but need to be configured Andy - use end-end frag on CE rather than UNI-NNI Mark Townsley L2TPv3 update A number of clarifications made Request publish update to sister PPP doc and move to last call shortly after this meeting Mitsuru Higashiyama - Ethernet over BCP over L2TP vs Ethernet over PWE3 PWE3 WG does not cover LAN to LAN compulsary tunnel LAN to LAN voluntary tunnel competes with PWE3 Asked for opinion on whether he should keep comp & vol and let vol & Ethernet over PWE3 co-exist. Comments: Discussion on whether there is enough WG interest to continue working on this draft unknown - The draft is potentially interesting for the DSL and ISDN use cases Comment has use for DSL and ISL apps, needs discussion on list Tmima Koren L2TP HC Thomas Narten: Alloc of IP protocol number a problem. IESG will push back strongly in general, and because one already issued for L2TP. Mark: Could use L2TPv3 at cost of extra 4 bytes, otherwise identify PID for session in setup negotiation. This is NAT unfriendly. Thomas: Discomfort at neg PIDs on fly - firewall issue will restrict use. Existing protocols do not do this - doubts Mark: use l2tpv3 would be a great approach but need input if this will put intended apps over the edge Tmima - not a lot of difference but extra overhead a problem of competing against other technologies (ATM I think). Can we negotiate away L2TP session id Mark: Yes, but could not support any demux Stewart/Mark that means that HC must use UDP control channel because loose sesson ID. Will ask Andy to spin new version with these comments.
