Abstract
A novel method for replicating and filtering multicast packet in a physical network is provided. Upon receiving a packet, the method generates a set of metadata as ingress replication context for the received packet based on the content of the receive packet. The generated ingress replication context includes a multicast group identifier, a replication identifier, a first layer exclusion identifier, and a second layer exclusion identifier. The method performs multicast replication of the packet by identifying logical ports and/or logical domains that are to be excluded from the multicast replication based on the content of the generated ingress replication context.
