Abstract: In one embodiment, a device in a network identifies a shortest path tree for a point of local repair in the network that excludes at least one link between the point of local repair and a neighbor of the point of local repair in the network. The device evaluates member nodes of a branch of the shortest path tree, to form a list of repair segments. The device further causes one or more segment routing labels to be added to a header of a packet based on the repair segment list and in response to a failure in the network associated with the at least one link excluded from the shortest path tree.
