[15:21:05] <david.sinicrope> IP address owned by both routers and should be advertised by IGP or IGP -TE from both routers
[15:21:10] <Y(J)S> I need to fill the chairs in regarding cong-cons ...

[15:21:40] <Andy Malis> David Black took care of that for you!
[15:22:31] <Y(J)S> Oh - great. David, Bob and I will be Skyping after this session
[15:22:40] <david.sinicrope> Forwarding state on Protector slide
[15:22:41] <Andy Malis> Yes, that's what he said.

[15:25:00] <david.sinicrope> Next Steps slide
[15:25:57] <david.sinicrope> Andy: read draft poll:  several out of 25.  several agree ready for WG adoption.  Adoption poll will run on list.  Andy has been ack'd in draft so Matthew will run poll.
[15:26:21] <david.sinicrope> Loa on Shepherd's report on dynamic ms pw draft
[15:27:24] <david.sinicrope> May not normally do reporting on shepherds activities but this time not part of wg leadership so wanted to give an update.  All involved in the WG are involved in the draft so needed someone with a fresh look
[15:27:49] <david.sinicrope> external person from wg not unusual to appoint as shepherd
[15:28:01] <david.sinicrope> shepherd review slide
[15:28:18] <david.sinicrope> -17 folks on draft including the Chairs
[15:28:27] <david.sinicrope> bad example of merging a few drafts
[15:28:50] <david.sinicrope> Loooooooooong list of nits
[15:29:12] <david.sinicrope> many result from the merging of drafts.
[15:29:48] <david.sinicrope> first draft from 2006 and indiv drafts from 2004.... a decade of work
[15:29:51] <david.sinicrope> IPR poll slide
[15:29:55] <david.sinicrope> real problem
[15:30:02] <david.sinicrope> 20 co-authors
[15:30:27] <david.sinicrope> Hard to find authors since work has lasted so long
[15:31:31] <david.sinicrope> can't remove person from author list - that wouldn't work
[15:31:55] <david.sinicrope> each author has influence such that their IPR could be ncluded and then not disclosed
[15:32:31] <david.sinicrope> Matthew: 2 outstanding responses, a few more came int eh last couple of days
[15:32:48] <Y(J)S> I think that according to the new diversity rules Loa needs to say he or she even if there are no she's on the author list ...
[15:32:52] <david.sinicrope> Most folks accounted for, but some still on vacation
[15:33:04] <david.sinicrope> Scott Bradner:  20 co-authors but only 3 on first page
[15:33:05] joins the room
[15:33:39] <david.sinicrope> <actually Scott asked and the 3 on the first page was the answer>
[15:33:59] <david.sinicrope> If they all don't answer Stewart will harass Loa by phone
[15:34:11] <david.sinicrope> Shepherd Write Up slide
[15:35:12] <david.sinicrope> given 20 authors support for work should be good
[15:35:31] <david.sinicrope> Andy: comment from Loa and AD - ANYONE can be a document shepherd
[15:36:20] <david.sinicrope> If anyone interested, please volunteer.  Good training for WG Chair to learn administrative details.
[15:37:04] <david.sinicrope> Stewart:  Also gives person some visibility. Shepherd ensures that authors address comments and chase them down.
[15:37:44] <david.sinicrope> Keyed IPv6 Tunnels - Wim
[15:38:06] <david.sinicrope> Slide 1 - filling in for Giles
[15:38:24] <Andy Malis> There's only one slide on this one
[15:38:43] <david.sinicrope> Draft not for PW working group.. Should be on L2TPEXT working group.  However given PW expertise here decided to present here.
[15:38:52] <david.sinicrope> <but it's still slide 1>
[15:39:39] <david.sinicrope> can work without the session ID.  Described in the draft
[15:40:22] <david.sinicrope> Use PW OAM mechanisms for failure detection
[15:40:44] <david.sinicrope> comment on L2TPEXT mailing list
[15:40:58] <david.sinicrope> solution implemented by multiple vendors and deployed.  Informational draft
[15:41:23] <david.sinicrope> Andy: if its deployed why infomrational rather than standards track?
[15:41:35] <david.sinicrope> Wim: because we don't change any protocol, just show the way it is used.
[15:41:36] <Y(J)S> So this draft is only to document an already deployed method ?
[15:41:56] <Y(J)S> If not, there are other (better) ways of doing this
[15:41:56] <david.sinicrope> I"m up
[15:42:03] <Andy Malis> I'll be taking minutes
[15:42:30] <Andy Malis> David is presenting the liaison from SG15 Q10 and Q12
[15:42:43] <Andy Malis> The figure is the important part
[15:43:47] <Andy Malis> The questions noticed that there's not much clarity on which combinations of p2p SS and MS PWs and p2mp PWs are valid
[15:44:43] <Andy Malis> Greg Mirsky - Ne needs a clarification - what kind of a PW maps to a P2MP PW, given that in MPLS-TP there may not be an IP return path?
[15:44:45] <Y(J)S> actually p2mp over p2p doesn't make sense, p2p can be p2mp - why not ?
[15:45:05] <Y(J)S> (should have been p2p can be OVER p2mp)
[15:45:17] <Andy Malis> Dave - we need to provide additional clarifications in the P2MP requirements draft to what combinations make sense and which don't
[15:45:51] <Andy Malis> Dave - additional clarity on these combations would be appreciated
[15:46:23] <Andy Malis> Btewart - woudln't the most interesting one be P2P MS SW over a P2MP LSP, which isn't in there?
[15:46:39] <Andy Malis> Stewart - so we could make progress on the document, and make it simpler?
[15:47:25] <david.sinicrope> We need to provide clarification of how p2mp pw can be combined with LSPs
[15:48:13] <Andy Malis> A comment that agrees that we need to remove the P2MP MS PW case
[15:48:34] <david.sinicrope> Matthew: Focus on the p2mp ss pw case and should be able to build from that.
[15:48:48] <david.sinicrope> If that is done, then gives clarity to the models
[15:48:54] <Andy Malis> Stewart - then models 1, 2, and 3 don't exist
[15:49:42] <Andy Malis> Dave - They don't explicitly ask for a response, but the clarification provided by December would be helpful
[15:49:58] <Andy Malis> Matthew-  we'll work on a response with the editors of the P2MP editors
[15:50:05] <david.sinicrope> Editors of the p2mp should draft a response for the Dec Q12 meeting
[15:50:13] <david.sinicrope> Andy adjourned the meeting.
[15:50:24] <Y(J)S> PWE3 session duration decreases each time
[15:50:44] <Andy Malis> That question was Yuji Kamite
[15:50:52] giles_heron leaves the room
[15:50:54] <Andy Malis> was from Yuji
[15:50:59] <Andy Malis> And we're done!
[15:51:19] Andy Malis leaves the room
[15:51:42] Y(J)S leaves the room
[15:52:04] KY leaves the room
[15:52:20] Guillaume Leclanche leaves the room: I'm happy Miranda IM user. Get it at
[15:53:29] david.sinicrope leaves the room
[20:22:09] leaves the room
