RFC 8537 Title: Updates to the Fast Reroute Procedures for Co-routed Associated Bidirectional Label Switched Paths (LSPs) Author: R. Gandhi, Ed., H. Shah, J. Whittaker Status: Standards Track Stream: IETF Date: February 2019 Mailbox: rgandhi@cisco.com, hshah@ciena.com, jeremy.whittaker@verizon.com Pages: 16 Characters: 36970 Updates: RFC 4090, RFC 7551 I-D Tag: draft-ietf-teas-assoc-corouted-bidir-frr-07.txt URL: https://www.rfc-editor.org/info/rfc8537 DOI: 10.17487/RFC8537 Resource Reservation Protocol (RSVP) association signaling can be used to bind two unidirectional Label Switched Paths (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 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 fast reroute 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. This document is a product of the Traffic Engineering Architecture and Signaling Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
