Abstract:
   Segment routing supports the creation of explicit paths using Adj-
   Segment-ID (SID), Node-SIDs, and BSIDs.  It is important to provide
   fast reroute (FRR) mechanisms to respond to failures of links and
   nodes in the Segment-Routed Traffic-Engineered(SR-TE) path.  A point
   of local repair (PLR) can provide FRR protection against the failure
   of a link in an SR-TE path by examining only the first (top) label in
   the SR label stack.  In order to protect against the failure of a
   node, a PLR may need to examine the second label in the stack as
   well, in order to determine SR-TE path beyond the failed node.  This
   document specifies how a PLR can use the first and second label in
   the SR-MPLS label stack describing an SR-TE path to provide
   protection against node failures.
