Abstract

This document specifies the use of Topology Independent Loop-FreeAlternate (TI-LFA) mechanisms with Multicast-only Fast Reroute(MoFRR) for Protocol Independent Multicast (PIM). The TI-LFA providesFast Reroute (FRR) protection for unicast traffic in IP networks byprecomputing backup paths that avoid potential failures. Byintegrating TI-LFA with MoFRR, this document extends the benefits ofFRR mechanisms to multicast traffic, enabling enhanced resilience andminimized packet loss in multicast networks. The document outlines anoptional approach to implement TI-LFA in conjunction with MoFRR forPIM, ensuring that multicast traffic is rapidly rerouted in the eventof a failure.
