      <abstract>
	 <t>   The current SR FRR such as TI-LFA provides fast re-route protection
   for the failure of a node on an SR-MPLS path by the neighbor upstream
   node as point of local repair (PLR) of the failed node.  However,
   once the IGP converges, the SR FRR is no longer sufficient to forward
   traffic of the path around the failure, since the non-neighbor
   upstream node of the failed node will no longer have a route to the
   failed node.  This document describes a simple mechanism to extend
   the fast re-route protection for the failure on an SR-MPLS path after
   the IGP converges.  The mechanism protects the node SID, adjacency
   SID and binding SID of the failed node on the path.
