Abstract
The present disclosure provides systems, methods and computer-readable media for maintaining network connectivity, in a LISP based network, when one or more network edge nodes lose connectivity to a LISP control plane of the network, using multicast messaging. In one example, a method includes receiving a connection request from a first endpoint to a second endpoint communicatively coupled to a second edge node; determining, by the first edge node, that a connection session to a control plane for locating the second endpoint has failed; querying one or more available edge nodes for locating the second endpoint using a multicast message; locating the second endpoint based on at least one query response received from the one or more available edge nodes, at least one query response including an identifier of the second endpoint; and establishing the connection request between the first endpoint and the second endpoint upon locating the second endpoint.
