Abstract
A method apparatus and computer readable medium for preforming SPB-PIM multicast interactions is presented. A Backbone Edge Bridge (BEB) in a Shortest Path Bridging (SPB) network discovers a multicast stream originating within a Protocol-Independent Multicast (PIM) network. The BEB sends multicast information to a Rendezvous Point (RP) in the PIM network. The BEB advertises a multicast stream learned from the RP into the SPB network. The BEB receives an update that includes a receiver interest in said multicast stream and initiates PIM join procedures for permitting the receiver to receive the multicast stream.
