Interim Meeting Summary.1 NOTES: 02SoftwiresInterimNotes.html Reviewed some current deployments –KDDI, Freenet6 Reviewed Security Analysis Criteria for selection was evaluated based on MUSTs from Problem Statement –ATS6, TSP, L2TPv3 were proposed as solutions for Hub & Spoke –V4overV6 and tunnel saf were proposed as solutions for Mesh

Interim Meeting Conclusions.1 1.Attendees reached consensus on solutions for both scenarios L2TPv2 was selected as Phase 1 solution for H&S L2TPv3 was selected as Phase 2 solution for H&S Combined MPBGP solutions from Yong Cui and C. Metz was selected for Mesh solution 2.Attendees reached conclusion on next steps Phase 1 Framework solution for H&S to be written immediately How to solve H&S scenarios w/ L2TPv2 Phase 2 Framework solution for H&S to be presented as soon as Phase 1 is documented How to solve all H&S requirements w/ L2TPv3 and propose extensions Create Framework doc for solutions to Mesh scenario How to solve all Mesh requirements w/ MPBGP and propose extensions Adopt Multicast solution by Shepherd, Wu, Li, Farinacci as WG doc Adopt security analysis and radius extensions as WG docs

Interim Meeting Conclusions.2 Meeting continued second day w/ break out sessions on two scenarios Proposed third interim meeting in “September” Discuss Framework for Phase 2 H&S List extension set for Phase 2 Finalize extension set for Mesh Meeting in Hong Kong was very successful Many thanks to hosts: CERNET and CHUK Many thanks to Mark Townsley (INT AD) for being present and keeping us to present and future process Rough consensus was achieved and notes posted to list

WG activities since the interim meeting The chairs posted on March 3rd a message with the title: "Notes and Consensus from Interim Meeting in Hong Kong". A number of clarification questions were asked on the mailing list since. Problem Statement draft at -01. Needs final, final edits in -02 (any second now) Softwire ML statistics since the interim meeting: –26 From: Jordi Palet Martinez –15 From: Alain Durand –12 From: Maria A.

Consensus Given that: –There was discussion involving many wg participants –No open issues considered remaining –Solution providers will represent a common vision in next presentations as stated in interim meeting notes and conclusion We declare rough working group consensus: –Hub & Spokes scenario: L2TPv2 chosen as the immediate solution L2TPv3 in phase 2 as a backward compatible upgrade –Mesh scenario: Conjoined effort for extensions to MPBGP based on work presented by Chris Metz and Yong Cui
