Abstract:
A method and apparatus for forwarding packets through a network domain that contains nodes that are label distribution protocol (LDP) enabled and nodes that are segment routing (SR) enabled. In one embodiment, the method may include a network node receiving a packet with a label attached thereto. The node swaps the label with a segment identifier (ID). The node then forwards the packet to an SR node. In another embodiment, the method may include a network node receiving a packet with a segment ID attached thereto. The node swaps the segment ID with a label. The node then forwards the packet to an LDP enabled node.
