Abstract:
A method is described to be implemented by a node in a network. The method is for selecting an endpoint for a maximally redundant tree-fast reroute (MRT-FRR) detour path to optimize detour path cost or length across the network. The method defines a set of steps including selecting a destination node and next hop failure to calculate detour paths. A clean set of nodes for the network is then calculated, where the clean set of nodes are nodes in the network that are not impacted in reaching the destination node by the failure in the given next hop. A candidate node for the endpoint of the detour p path is selected from the set of clean nodes based on any one of a plurality of configured options and forwarding of data packets is configured to the selected candidate as the endpoint of the detour path to the destination node.
