Abstract

A network device includes an interface and packet processing logic. The interface receives a multicast packet. The packet processing logic determines identifier data corresponding to the received multicast packet and replicates the identifier data to multiple outgoing packet forward engines at a first point in a processing path. The packet processing logic further replicates the identifier data to multiple data streams at a second point in the processing path and replicates the identifier data to multiple logical interfaces in the same stream at a third point in the processing path.
