Patent ID: 7865576

Claim:
A method of managing subscriber host information, comprising: receiving, at a first access server, a new or updated information about a subscriber host; determining whether the subscriber host is associated with a multi-chassis peering including multiple peer access servers each configured to provide the subscriber host access to network service(s); and in the event it is determined that the subscriber host is associated with a multi-chassis peering including multiple peer access servers each configured to provide the subscriber host access to network service(s), configuring the first peer chassis access server with a tag or other identifier associated with the multi-chassis peering to associate with a communication port with which the subscriber host is associated and propagating the new or updated information about the subscriber host to a peer chassis access server of the first access server associated with the multi-chassis peering, wherein said subscriber host information is propagated to said peer chassis access server via a communication path associated with said multi-chassis peering, wherein said communication path has associated with it an IP or other address specific to the multi-chassis peering; wherein said step of propagating the new or updated information about the subscriber host to a peer chassis access server is not performed if the new or updated information with respect to the subscriber host is received from a peer chassis access server of the multi-chassis peering.
