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.
