The IESG has approved the following document: - 'Loop-Free Alternates selection for Multi-Homed Prefixes' (draft-ietf-rtgwg-multihomed-prefix-lfa-09.txt) as Proposed Standard This document is the product of the Routing Area Working Group. The IESG contact persons are Alvaro Retana, Deborah Brungard and Martin Vigoureux. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-rtgwg-multihomed-prefix-lfa/ Technical Summary This document shares experience gained from implementing algorithms to determine Loop-Free Alternates for multi-homed prefixes. In particular, this document provides explicit inequalities that can be used to evaluate neighbors as a potential alternates for multi-homed prefixes. It also provides detailed criteria for evaluating potential alternates for external prefixes advertised by OSPF ASBRs. This documents updates and expands some of the "Routing Aspects" as specified in Section 6 of RFC5286. Working Group Summary This passed through the WG smoothly. Between the author team and the reviewers many of the subject matter experts have read the text and thus I have confidence that it is technically correct and a useful extension to the work published in RFC5286 Document Quality This is a clear and well written document. That enhances a widely implemented IP fast-reroute protocol. Personnel Stewart Bryant is the Document Shepherd. Martin Vigoureux is the Responsible Area Director
