1. A receiver in a multicast network, the receiver comprising:
one or more processors; and
one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the receiver to perform operations comprising:
transmitting an mtrace (*, G) route to a last hop router, wherein the last hop router is configured to forward the mtrace (*,G) route to a rendezvous point (RP);
receiving an active source list generated by the RP that comprises one or more sources configured to transmit multicast traffic; and
creating an mtrace (S,G) route for the RP to initiate based on the received active source list.
