Abstract:
Segment Routing Traffic Engineering (SR-TE) supports explicit paths
using segment lists containing adjacency-SIDs, node-SIDs and binding-
SIDs. The current SR FRR such as TI-LFA provides fast re-route
protection for the failure of a node along a SR-TE path by the direct
neighbor or say point of local repair (PLR) to the failure. However,
once the IGP converges, the SR FRR is no longer sufficient to forward
traffic of the path around the failure, since the non-neighbors of
the failure will no longer have a route to the failed node. This
document describes a mechanism for fast re-route protection against
the failure of a SR-TE path after the IGP converges. It provides
fast re-route protection for an adjacency segment, a node segment and
a binding segment of the path.
Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
