Abstract
One embodiment of the present invention provides a switch. The switch includes a processor and a computer-readable storage medium. The computer-readable storage medium stores instructions which when executed by the processor cause the processor to perform a method. The method comprises determining whether the switch is a leaf switch of a multicast distribution tree of a multicast group based on a multicast topology query message from a root switch of the multicast distribution tree. If the switch is a leaf switch, the method further comprises constructing a multicast topology report message comprising layer-2 topology information of the multicast group associated with the switch.
