The IESG has approved the following document: - 'Updates to the Fast Reroute Procedures for Co-routed Associated Bidirectional Label Switched Paths (LSPs)' (draft-ietf-teas-assoc-corouted-bidir-frr-07.txt) as Proposed Standard This document is the product of the Traffic Engineering Architecture and Signaling Working Group. The IESG contact persons are Alvaro Retana, Martin Vigoureux and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-teas-assoc-corouted-bidir-frr/ Technical Summary Resource Reservation Protocol (RSVP) association signaling can be used to bind two unidirectional LSPs into an associated bidirectional LSP. When an associated bidirectional LSP is co-routed, the reverse LSP follows the same path as its forward LSP. This document updates the Fast Reroute (FRR) procedures defined in RFC 4090 to support both single-sided and double-sided provisioned associated bidirectional LSPs. This document also updates the procedure for associating two reverse LSPs defined in RFC 7551 to support co-routed bidirectional LSPs. The FRR procedures can ensure that for the co-routed LSPs, traffic flows on co-routed paths in the forward and reverse directions after a failure event. Working Group Summary The progress of the document through the WG has been smooth. Document Quality The base (G)MPLS RSVP protocol has been implemented. The procedures discussed in this document are compatible with earlier implementations. While there have been no public statements on implementation, the authors are from multiple vendors, and implementation is expected. Personnel Who is the Document Shepherd for this document?
