Abstract:
   Segment Routing Traffic Engineering (SR-TE) supports explicit paths
   using segment lists containing adjacency-SIDs, node-SIDs and binding-
   SIDs.  The current SR FRR such as TI-LFA provides fast re-route
   protection for the failure of a node along a SR-TE path by the direct
   neighbor or say point of local repair (PLR) to the failure.  However,
   once the IGP converges, the SR FRR is no longer sufficient to forward
   traffic of the path around the failure, since the non-neighbors of
   the failure will no longer have a route to the failed node.  This
   document describes a mechanism for the restoration of the routes to
   the failure of a SR-MPLS TE path after the IGP converges.  It
   provides the restoration of the routes to an adjacency segment, a
   node segment and a binding segment of the path.  With the restoration
   of the routes to the failure, the traffic is continuously sent to the
   neighbor of the failure after the IGP converges.  The neighbor as a
   PLR fast re-routes the traffic around the failure.
