-          No comments.

3. RT-Constrain Lite for Provider Edge Routers

Marshall Eubank: You're not asking for any contribution from this working group?

John Scudder: That’s correct, this is an FYI as this is happening in IDR.

4. Extranet in BGP Multicast VPN

Marshall Eubank: Are you looking to the WG to resolve these options.

Rahul Aggarwal: Feedback is good. The authors discussed this with service providers. We would intend to sort which options are a MUST or a SHOULD, but there’s nothing to be resolved. Any comments?

Danny McPherson:  No other comments?  OK.

5. Multicast VPN fast upstream failover

Danny McPherson:  Will take the request to the mailing list.

6. Multicast in MPLS/BGP IP VPN Configuration BGP Extended Communities

Mark Fine: Would like comments.

Marshall Eubank: Are you saying that messages should be sent, for the system log?

Mark Fine: More of a question, if we fail the discovery process.

Danny McPherson: Best if you send an email to the list regarding these last few open issues you noted during your presentation.

7. Use of Wildcard in S-PMSI Auto-Discovery Routes

IJsbrand Wijnands: Wild card S-PMSI's are already documented for some time. What is different in this draft?

Yakov Rekhter: Let's say we agree to disagree on that. I sent specific comments back to Eric regarding his comments. Please read those comments on the [mailing] list.

IJsbrand Wijnands: I read those. This draft does seem to overlap and it does not reference Eric’s draft. If you think this is different it would be good to state this.

Yakov Rekhter: Please read my comments. It's clear.

IJsbrand Wijnands: I read those. It would be good if you spell the differences out in the draft.

Yakov Rekhter: I do not think it's necessary. With respect to encoding, in both this draft and draft-rosen, uses' encoding that is specified in MBGP spec. They only difference is the use of 0/0 for wild cards. The use of using 0/0 for all match semantics predates draft-rosen. There is nothing original in draft-rosen encoding.

Rahul Aggarwal: Comparing these documents is mute. They have two different starting points.  Please read Yaakov's comments.

Danny McPherson: Yakov, what’s your intention for this draft currently?

Yakov Rekhter: We are not requesting this become a WG document yet. We would appreciate comments.

Danny McPherson: If you have comments please send them to the list.

8. AOB

8.1 Charter Discussion


Marshall Eubank: All the WG action items are done. The question is will we close the group, or recharter?

Ross Callon: The considerations draft is a working group document. At a minimum we should add this as a milestone. This is easy to do, if the chairs, WG and AD think it’s a good idea we can add it as milestone. If the chairs and the group feel there is more work beyond the considerations draft. It seems to more that there could be more work on multicast.

Danny McPherson: There is work. There are things that need to be considered. We should revisit our milestones now that the MVPN documents have been submitted to the IESG, that was a gate for an official new work in the WG, now we can consider new work items. 

Marshall Eubank: Is there anyone that does not think the considerations document should not become a milestone? [no objections from WG attendees] Ok, we will take this to the list.

Thomas Morin: There are new multicast proposals for the WG, and one document that stems from requirements in the Multicast VPN Requirements RFC. It seems to make sense to add this as a WG item.

Danny & Marshall: Yes, that’s good. [To WG audience] please submit suggestions for the new milestones and charter.
