Abstract
In one embodiment, a relay device of a network, which is reachable by a source device via only a non-multicast network, receives a non-multicast that encapsulates a multicast message. The relay device is connected to a sub-network of one or more devices. The relay device decapsulates the unicast message to determine the multicast message, re-encapsulates the multicast message as a relay-sourced multicast message, and multicasts the relay-sourced multicast message to the one or more devices within the sub-network.
