Abstract
A method and apparatus for providing Protocol-Independent Multicast (PIM) snooping for a Shortest Path Bridging Multicast (SPBM) Network is presented. An ingress Backbone Edge Bridge (BEB) device of a Shortest Path Bridging (SPB) network having at least one egress BEB coupled to at least one PIM network performs the following operations. The egress BEB, snoops join and prune messages for a multicast stream in the SPB network. A multicast tree is built in the SPB network for the multicast stream in accordance with the join and prune messages. The multicast stream is forwarded through the SPB network in accordance with the multicast tree.
