Apparatus, system, and method for topology discovery across geographically redundant gateway devices

Abstract:

A disclosed method may include (1) receiving, at a local gateway device included in a network, a query message that initiates a topology discovery process from a remote gateway device included in the network, (2) identifying, within the query message, at least one characteristic of a first interface included on the remote gateway device, (3) selecting, for the first interface, a second interface included on the local gateway device based at least in part on the characteristic of the first interface identified within the query message, and then (4) sending, to the remote gateway device, a response message that (A) includes at least one characteristic of the second interface included on the local gateway device and (B) enables the remote gateway device to map the first interface to the second interface in connection with the topology discovery process. Various other apparatuses, systems, and methods are also disclosed.
