The IESG has approved the following document: - 'Remote-LFA Node Protection and Manageability' (draft-ietf-rtgwg-rlfa-node-protection-13.txt) as Proposed Standard This document is the product of the Routing Area Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-rtgwg-rlfa-node-protection/ Technical Summary 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. Working Group Summary There was strong concensus for this document by the working group, the routing directorate review by Mike Shand and comments by Levente Csikor helped resolve some earlier issues with the drafts readability. Document Quality The document is of high quality and there is an existing implementation that has been deployed. Personnel Jon Mitchell, Document Shepherd Alia Atlas, Responsible Area Director
