   This document updates RFC 4090 for the Resource Reservation Protocol
   (RSVP) Traffic-Engineering (TE) procedures defined for facility
   backup protection.  The updates include extensions that reduce the
   amount of signaling and processing that occurs during Fast Reroute
   (FRR), and subsequently, improves scalability when undergoing FRR
   convergence after a link or node failure.  These extensions allow the
   RSVP message exchange between the Point of Local Repair (PLR) and the
   Merge Point (MP) to be independent of the number of protected Label
   Switched Paths (LSPs) traversing between them when facility bypass
   FRR protection is used.  The signaling extensions are fully backwards
   compatible with nodes that do not support them.
