Abstract:
   Segment routing supports the creation of explicit paths using
   adjacency-sids, node-sids, and binding-sids.  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 label stack describing an SR-TE path to provide protection
   against node failures.
