Technical Summary
This document specifies the use of Topology Independent Loop-Free
Alternate (TI-LFA) mechanisms with Multicast Only Fast ReRoute
(MoFRR) for Protocol Independent Multicast (PIM). TI-LFA provides
fast reroute protection for unicast traffic in IP networks by
precomputing backup paths that avoid potential failures. By
integrating TI-LFA with MoFRR, this document extends the benefits of
fast reroute mechanisms to multicast traffic, enabling enhanced
resilience and minimized packet loss in multicast networks. The
document outlines the necessary protocol extensions and operational
considerations to implement TI-LFA in conjunction with MoFRR for
PIM, ensuring that multicast traffic is rapidly rerouted in the
event of a failure.
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 special observations to mention. There was broad agreement. Good support for the document, no one against it.
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?
Nothing special observations that need mentioning.
Due to a very late technical findings the document rerun IETF LC and IESG ballot
