Abstract:
1. A method comprising: receiving, with a network device of a network, configuration information that specifies first and second constituent links for a layer two (L2) aggregated interface, wherein the first and second constituent links are physical links connected to respective physical interfaces of the network device; generating, with the network device, a link state message that specifies layer three (L3) routing information associated with the aggregated interface and includes a first sub-type-length-value (sub-TLV) that specifies an attribute of the first constituent link of the aggregated interface and a second sub-type-length-value (sub-TLV) that specifies an attribute of the second constituent link of the aggregated interface; and sending the link state message from the network device to another network device of the network in accordance with a routing protocol.
