The IESG has received a request from the Protocols for IP Multicast WG (pim)
to consider the following document: - 'Multicast-only Fast Reroute Based on
Topology Independent Loop-free
   Alternate Fast Reroute'
  <draft-ietf-pim-mofrr-tilfa-05.txt> as Informational RFC

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2024-09-23. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract


   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.
