Abstract

An example method is provided and may include multicasting a discovery packet in an overlay network, which includes a Layer 2 scheme over a Layer 3 network; and identifying endpoints based on their respective responses to the discovery packet, where the endpoints are coupled across a multicast backbone. In more specific embodiments, the method may include identifying disconnected endpoints in the overlay network based on a lack of responses from the disconnected endpoints.
