Added reference and text in Section 1 for PCE initiated bidirectional LSPs
Move definition of Forward LSPs to terminology Section
Added Section 3.2 and 4.1.1 on node protection bypass tunnels
Added usage of path errors in Section 4.1
Added Section 4.1.2 on unidirectional link failures
Added Section 4.1.3 on revertive behavior after FRR
Added Section 4.1.4 on bypass tunnel provisioning
Various editorial changes

We welcome your review comments and suggestions.

    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
       describes Fast Reroute (FRR) procedures for both single-sided and
       double-sided provisioned associated 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.

    Please note that it may take a couple of minutes from the time of submission
    until the htmlized version and diff are available at tools.ietf.org.
