Abstract
In one embodiment, a method includes transmitting a packet from a router located in a communication path between a source and a receiver, the packet having one or more values used to select a group designated router from a list of candidate group designated routers for multicast traffic streams, selecting the router as said group designated router for one or more of the multicast traffic streams, and forwarding traffic for the one or more multicast traffic streams to the receiver. The candidate group designated routers are last hop routers for transmitting the multicast traffic streams to a common link connected to the receiver. An apparatus is also disclosed herein.
