Abstract

Disclosed is an apparatus and method for segment routing using a remote forwarding adjacency identifier. In one embodiment, a first node in a network receives a packet, wherein the packet is received with a first segment-ID and another segment ID attached thereto. The first node detaches the first and the other segment IDs from the packet. Then the first node attaches a first label to the packet. Eventually, the first node forwards the packet with the attached first label directly to a second node in the network. In one embodiment, the other segment ID corresponds to a forwarding adjacency or tunnel label switched path between the first node and another node.
