Abstract:
   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.
