Abstract
A head-end node in a Segment Routing network includes circuitry configured to detect a failure of a Segment Routing policy, set an eligibility flag for the candidate path associated with the Segment Routing policy to false, and, if one or more other candidate paths exist for the Segment Routing policy, switch to another candidate path of the one or more other candidate paths considering corresponding eligibility flags for the one or more other candidate paths. The eligibility flag and the corresponding eligibility flags are maintained by the head-end node for the candidate path and the one or more other candidate paths such that the head-end node selects a path based thereon.
