Abstract Abstract
Segment Routing Traffic Engineering (SR-TE) supports the creation of Segment Routing Traffic Engineering (SR-TE) supports the creation of
explicit paths using segment lists containing adjacency-sids, node- explicit paths using segment lists containing adjacency-sids, node-
sids, anycast-sids, and binding-sids. When the segment list defining sids, anycast-sids, and binding-sids. When the segment list defining
an SR-TE path contains a node-sid, and the node fails, the network an SR-TE path contains a node-sid, and the node fails, the network
may no longer be able to properly forward traffic on that SR-TE path. may no longer be able to properly forward traffic on that SR-TE path.
