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.
