Abstract
A method is described and in one embodiment includes identifying at an initiator element a list of Internet protocol ('IP') prefixes corresponding to routes designated as interesting routes, wherein the IP prefixes are included in a Routing Information Base ('RIB') of the initiator; monitoring the RIB for a change in the list of IP prefixes; and, responsive to detection of a change in the list of IP prefixes, injecting at least a portion of the changed list of IP prefixes into a payload of an IKEv2 NOTIFY message and sending the IKEv2 NOTIFY message to a responder element peered with the initiator element, wherein the responder element updates an RIB of the responder element using the IP prefixes included in the received IKEv2 NOTIFY message.
