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.
