Abstract:

   This document describes the mechanism and operational guidelines for
   fast protecting the egress node and link of a Segment Routing for
   IPv6 (SRv6) path.  Topology Independent Loop-Free Alternate (TI-LFA)
   specifies fast protections for transit nodes and links of an SR path,
   but does not present protections for the egress node.  The solution
   uses a Mirror SID (End.M) behavior to steer traffic to a protector
   egress upon failure of the primary egress.  The Interior Gateway
   Protocol (IGP) (IS-IS/OSPFv3) extensions used to advertise the Mirror
   SID and protected locators are specified in
   [I-D.he-lsr-srv6-mirror-sid-igp-encoding]; they build on the IS-IS
   and OSPFv3 SRv6 extensions defined in [RFC9352] and [RFC9513].
