The IESG has approved the following document: - 'IGP Unreachable Prefix Announcement' (draft-ietf-lsr-igp-ureach-prefix-announce-11.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-igp-ureach-prefix-announce/ Technical Summary Summarization is often used in multi-area or multi-domain networks to improve network efficiency and scalability. With summarization in place, there is a need to signal loss of reachability to an individual prefix covered by the summary. This enables fast convergence by steering traffic away from the node which owns the prefix and is no longer reachable. This document describes how to use the existing protocol mechanisms in IS-IS and OSPF, together with the two new flags, to advertise such prefix reachability loss. Working Group Summary Working group consensus to move this document forward. One participant felt strongly against moving the document forward on technical grounds. These were reviewed by the responsible AD, as well as the IESG during appeal, and found to have been adequately addressed by the working group and document authors. Other objections were also addressed and these are fully documented in the shepherd writeup. Document Quality Multiple vendor implementations. There are known implementations of the mechanism defined in this document. Personnel The Document Shepherd for this document is Yingzhen Qu. The Responsible Area Director is Jim Guichard. _______________________________________________ Lsr mailing list -- [email protected] To unsubscribe send an email to [email protected]
