Abstract:
A network component comprising at least one processor configured to implement a method comprising receiving a packet, determining whether the packet comprises a topology label, and adding the topology label to the packet if the packet does not comprise the topology label. Included is a method comprising routing a plurality of packets corresponding to a plurality of forwarding equivalence classes (FECs) over a plurality of network topologies using a topology label and plurality of forwarding labels for each network topology. Also included is a network comprising a plurality of nodes in communication with each other and having a plurality of network topologies, wherein at least some of the nodes are configured to route data packets for a plurality of FECs along a path in each network topology using a topology label corresponding to each network topology and an inner label corresponding to each FEC.
