The IESG has approved the following document: - 'Advertising Unreachable Links in OSPF' (draft-ietf-lsr-ospf-ls-link-infinity-25.txt) as Proposed Standard
This document is the product of the Link State Routing Working Group. The IESG contact persons are Gunter Van de Velde, Jim Guichard and Ketan Talaulikar. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-lsr-ospf-ls-link-infinity/ Technical Summary In certain scenarios, it is necessary to advertise OSPF links that are not applicable to the default SPF (Shortest Path First) calculation for other purposes. In order to advertise these links and not use them in the base SPF calculation, the metric LSLinkInfinity (0xffff) is used to specify that the link is unreachable. MaxReachableLinkMetric (0xfffe) is defined to provide backward compatible reachability in specifications that previously specified advertisement of MaxLinkMetric (0xffff). This document updates RFC 5443, RFC 6987, and RFC 8770 with respect to the advertisement of MaxReachableLinkMetric (0xfffe) rather than MaxLinkMetric (0xffff). Working Group Summary Was there anything in the WG process that is worth noting? For example, was there controversy about particular points or were there decisions where the consensus was particularly rough? No controversy. Document Quality Are there existing implementations of the protocol? Have a significant number of vendors indicated their plan to implement the specification? Are there any reviewers that merit special mention as having done a thorough review, e.g., one that resulted in important changes or a conclusion that the document had no substantive issues? If there was a MIB Doctor, Media Type, or other Expert Review, what was its course (briefly)? In the case of a Media Type Review, on what date was the request posted? There are no implementations of this document. This is an OSPF protocol extension, so no reviews from other WGs are required. The document includes a YANG data model, which has been reviewed by a YANG doctor. Personnel The Document Shepherd for this document is Yingzhen Qu. The Responsible Area Director is Gunter Van de Velde.
