The IESG has approved the following document: - 'Micro-loop prevention by introducing a local convergence delay' (draft-ietf-rtgwg-uloop-delay-09.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-uloop-delay/ Technical Summary Transient forwarding loops can occur among routers using hop-by-hop forwarding. This document describes a mechanism for link-state routing protocols to prevent local transient forwarding loops in case of link failure. This mechanism proposes a two-steps convergence by introducing a delay between the convergence of the router adjacent to the topology change and the network wide convergence. Working Group Summary The final version of the document has strong consensus in the WG. Input from the WG was incorporated in the document, which affected both the scope and substance of the document. Document Quality he document is of high quality. A Routing Area Directorate early review of draft-ietf-rtgwg-uloop-delay-01 was done by Matthew Bocci. It noted mainly grammatical problems, as well as a requesting a few technical clarifications. draft-ietf-rtgwg-uloop-delay-03 addressed both the grammatical and technical clarifications from the review. As discussed in the document, the mechanism described has at least three implementation and has been deployed in live networks.
