ABSTRACT:
A method is provided in one example implementation and includes sending a PIM join message to the second spoke router by the hub router. The second spoke router dynamically determines each interested remote spoke router by parsing a hub-sent PIM message and accordingly constructs the multicast routing entry such that the first and second spoke routers establish multicast communication independent of a hub router. In more specific embodiments, the PIM join/prune messaging includes a list of each downstream spoke router that sent a PIM join/prune, in a new attribute. The PIM join/prune message is sent by the hub router towards a multicast source. A new receiver-list attribute is created that the hub router populates with a non-broadcast multi-access (NBMA) address for each interested spoke router.
