| Zusammenfassung: | One embodiment of the present invention provides a switch. The switch includes an inter-switch multicast module and an edge multicast module. The inter-switch multicast module identifies for a first replication of a multicast packet an egress inter-switch port in a multicast tree rooted at the switch. The multicast tree is identified by an identifier of the switch. The edge multicast module identifies an egress edge port for a second replication of the multicast packet based on a multicast group identifier. The multicast group identifier is local within the switch. |
