This document updates the Resource Reservation Protocol - Traffic
Engineering (RSVP-TE) Fast Reroute (FRR) procedures defined in
RFC 4090 to support Packet Switch Capable (PSC) Generalized
Multiprotocol Label Switching (GMPLS) Label Switched Paths (LSPs).
These updates allow the coordination of a bidirectional bypass tunnel
assignment protecting a common facility in both forward and reverse
directions of a co-routed bidirectional LSP. In addition, these
updates enable the redirection of bidirectional traffic onto bypass
tunnels that ensure the co-routing of data paths in the forward and
reverse directions after FRR and avoid RSVP soft-state timeout in the
control plane.
This document is a product of the Traffic Engineering Architecture and Signaling Working Group of the IETF.
This is now a Proposed Standard.
