The IESG has received a request from the Routing Area Working Group WG (rtgwg) to consider the following document: - 'Remote-LFA Node Protection and Manageability' <draft-ietf-rtgwg-rlfa-node-protection-08.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-01-11. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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.
