Abstract: In one embodiment, a method by a router in a multicast network for multicast mtrace extension to trace one or more any-source multicast (ASM) sources includes transmitting a mtrace (*,G) route to a last hop router, receiving an active source list, and creating a mtrace (S,G) route for a rendezvous point (RP) to initiate based on the received active source list.

Abstract: In one embodiment, a method by a router in a multicast network includes receiving a multicast trace query comprising a data packet, editing the multicast trace query to include data corresponding to the data packet, transmitting the edited multicast trace query to a subsequent router, transmitting a first message indicating the edited multicast trace query was transmitted to the subsequent router, and starting a timer for a determined period of time.
