Abstract:
   The loop-free alternates computed following the current Remote-LFA
   specification guarantees only link-protection.  The resulting Remote-
   LFA nexthops (also called PQ-nodes), may not guarantee node-
   protection for all destinations being protected by it.

   This document describes an extension to the Remote Loop-Free based IP
   fast reroute mechanisms, that specifes procedures for determining if
   a given PQ-node provides node-protection for a specific destination
   or not.  The document also shows how the same procedure can be
   utilized for collection of complete characteristics for alternate
   paths.  Knowledge about the characteristics of all alternate path is
   precursory to apply operator defined policy for eliminating paths not
   fitting constraints.
