Abstract
In one embodiment, a first Edge Device may join a multicast group via a multicast router, wherein the first Edge device is in a first site of a network and the multicast router is in a second site of the network. The first Edge Device may ascertain an existence of both a first multicast source in the first site of the network and a second multicast source in the second site of the network. The first Edge Device may select the first multicast source as a multicast source from which to receive multicast data for the multicast group. The first Edge Device may notify the second multicast source in the second site of the network that the first Edge Device is not interested in receiving multicast data for the multicast group from the second multicast source.
