Abstract: During operation, a layer-3 (L3) router can receive a trace query to trace multicast paths associated with a multicast group. In response to detecting a layer-2 (L2) switch coupled to the L3 router, the L3 router can construct a request packet and send the request packet to the coupled L2 switch.
