Abstract Abstract
Resource Reservation Protocol (RSVP) association signaling can be Resource Reservation Protocol (RSVP) association signaling can be
used to bind two unidirectional LSPs into an associated bidirectional used to bind two unidirectional LSPs into an associated bidirectional
LSP. When an associated bidirectional LSP is co-routed, the reverse LSP. When an associated bidirectional LSP is co-routed, the reverse
LSP follows the same path as its forward LSP. This document LSP follows the same path as its forward LSP. This document
describes Fast Reroute (FRR) procedures for both single-sided and describes Fast Reroute (FRR) procedures for both single-sided and
double-sided provisioned associated bidirectional LSPs. The FRR double-sided provisioned associated bidirectional LSPs. The FRR
procedures can ensure that for the co-routed LSPs, traffic flows on procedures can ensure that for the co-routed LSPs, traffic flows on
