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.
