1. 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.

11. A network provider equipment, comprising:
an inter-chassis communication interface; and
a processor coupled to the inter-chassis communication interface and configured to;receive, at a first access server, a new or updated information about a subscriber host; determine whether the subscriber host is associated with a multi-chassis peering; 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 propagate to a peer server of the first access server associated with the multi-chassis peering, via the inter-chassis communication interface, the new or updated information;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 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. - View Dependent Claims (12, 13)

14. A computer program product for managing subscriber information, the computer program product being embodied in a computer readable medium and comprising computer instructions for:
-
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 to a peer 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.
