Claim:
1. A method for selective multicast processing, the method comprising: establishing, at a backbone edge bridge (BEB), using one or more processors, an association between source address, group address (S, G) information of a data stream and a service instance identifier (ISID); programming, using the one or more processors, a classification engine in the BEB with a match that classifies a Virtual Local Area Network (VLAN), wherein the match includes a specific source address, group address (S, G) match that classifies a VLAN; listening, at the BEB, for a multicast ISID of interest to the BEB; determining that a multicast ISID of interest to the BEB is received at the BEB; de-encapsulating a mac-in-mac message from the multicast ISID of interest according to a corresponding multicast unique ISID and VLAN, wherein the de-encapsulating includes performing an (S,G) ternary content-addressable memory (TCAM) lookup to decide which source virtual port (SVP) to send the data stream to; and sending, from the BEB, the data stream to interested switches based on the ISID corresponding to the (S,G) matching.
