Abstract:
The loop-free alternates computed following the current Remote-LFA
[I-D.ietf-rtgwg-remote-lfa] specification gaurantees only link-
protection. The resulting Remote-LFA nexthops (also called PQ-
nodes), may not gaurantee node-protection for all destinations being
protected by it.
This document 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.
