Hi RTGWG members,

As suggested by Alia as part of the AD review, I have added a new section
on how to compute node-protecting R-LFA paths for destinations with
multiple ECMP primary nexthops, and uploaded the 09 version.

Request you to review the same and let us know your feedback and comments.

Thanks and Regards,
-Pushpasis

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 described in [RFC7490], that describes
   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 utilised 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.





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.
