Abstract:
A method implemented by a network element (NE) in a network, comprising receiving, by the NE, preferred path route (PPR) information describing a PPR graph, the PPR graph representing a plurality of PPRs between an ingress NE and an egress NE in the network, and updating, by the NE, a forwarding database to include a forwarding entry for the egress NE in response to identifying the NE in the plurality of PPR-PDEs, the forwarding entry indicating a next hop by which to forward a data packet comprising the PPR-ID.
