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.
