2.5.12 Routing Area Meeting (rtgarea)

Current Meeting Report


The Routing Area met in one session on Monday evening at the 60th IETF. These minutes are reported by Bill Fenner based on notes taken by himself and Alex Zinin.

The meeting started with the usual working group status reports.

BFD has several documents, some which will be ready in August, some which will be ready by the end of the year. They are in good shape on their charter; the biggest current work item is security. They hope to wrap up the work really fast.

Most of CCAMP's milestones are overdue, but a bunch of drafts are nearly ready to go to the IESG, so they are nearly completed. The working group drafts that have been blocking several others in the RFC-Editor's queue have all been through working group last call, and some have completed AD review; hopefully this backlog should clear in a couple of months. There has been a lot of work across working group boundaries, like ASON routing solutions and multi-area/multi-AS MPLS TE. Lots of interaction via liaisons with ITU-T. CCAMP plans to recharter, both to fix up the milestones and possibly to start work on Layer 1 VPNs.

Neither FORCES chair was present to give a status report.

IDMR is still hanging in there with the DVMRP spec to publish.

IDR delivered the BGP spec bundle to the IESG, and received comments back; this is expected to make it through soon. The working group has started accepting new work, so things are progressing along.

ISIS finished the TE spec, which was blocking several other documents. The Interoperable IP spec was published as an RFC. Graceful Restart is finished. The MIB is being finished, the recent issue was how to handle multiple instances. Work this meeting includes the experimental TLV, multi-topology ISIS, several new drafts.

MANET is nearly done with the experimental stage; 3 of the 4 documents to be published as experimental are RFCs; one is still going through the review process. The working group is still in the middle of the rechartering process, will to finish the details and submit to the ADs.

MPLS has two main things going on: OAM requirements and solutions, and point-to-multipoint TE. One milestone that the WG plans to put more cycles into is to advance LDP to Draft Standard. The spec needs to have some updates before being published as Draft Standard.

OSPF has published Graceful Restart, completed the OSPFv2 MIB, and several other WG documents are close to working group Last Call. The OSPFv3 Authentication spec has some issues but has good progress. A Design Team was formed to work on MANET extensions to OSPF and has some proposals for what kind of mechanisms there will be. New work is happening on multi-topology support for OSPF, similar to in ISIS. Kireeti has taken the task of documenting OSPF's requirements from IANA for registries.

PIM is finishing the sparse-mode spec. The Dense Mode spec made it through the IESG and will be published as Experimental. Bidirectional PIM and anycast RP are ready for IETF Last Call. The PIM MIB is progressing but needs help with IPv6. Would like to update the charter to include BGP-MPLS VPNs + point-to-multipoint LSPs.

RPSEC is moving forward on the generic threats draft; the generic requirements draft is ready for a WG Last Call. A BGP Requirements design team has been formed, and will present its initial results on Wednesday at the RPSEC WG meeting.

The RTGWG is a new working group, meeting for the first time this week. GTSM is being revised and will be republished as Proposed Standard. The IGP shortcut spec was approved as informational. IP Fast ReRoute is the major topic now. The working group plans to deliver two specs: "basic" and "enhanced" fast reroute.

SSM has one document left, which just needs some small updates and should be ready soon.

VRRP for IPv4 was approved as Draft Standard. VRRP for IPv6 has been waiting for implementations -- the good news is that there are now implementations; the bad news is that some issues were found so the spec needs some updates. On the MIB front, the WG decided to go with a single MIB covering both IPv4 and IPv6. There is still some interest in subsecond timers for VRRP but no activity yet.

The routing area itself has plans and milestones - closing old working groups (succeeded with BGMP, but IDMR is still holding on), creating BFD WG (done), and a BGP security WG in October.

Naiming Shen presented on IP Traffic Engineering (see presentation slides "ip-te-rsp" for details; the general idea is to use host routes to extra addresses assigned to routers to establish IP tunnels.)

Adrian Farrel: haven't you defined a layer 3 switching/label type which you could just slot into GMPLS and you're done?
Naiming: Not sure - let's talk offline.
Dmitri: The label assignment doesn't need to be done hop-by-hop in GMPLS.
Naiming: Does this need a tunnel?
Dmitri: Not necessarily. Define a new label type, see if label request object that you define here might fit inside GMPLS.
Alex: Dmitri, please send email to routing-discussion
Alex: How many read the draft? ~25%
Alex: How many think we should move it forward? few.
Dmitri: Idea is very interesting - do you say move forward the concept or the document?
Alex: who thinks we should pursue the concept? more.

Francois Le Faucheur presented on Connecting IPv6 Islands over IPv4 MPLS using IPv6 Provider Edge Routers (6PE) (see presentation slides "BGP-Tunnel" for details; the general idea is to tunnel IPv6 over an IPv4+MPLS backbone using multiprotocol BGP to identify tunnel endpoints)

Alex: Next steps: going through IDR, since it's a BGP extension.
Sue Hares: As someone who has seen this draft through several versions, I'm glad you took all the unused options out and this version is worthy of a good read.
