Abstract
A switch includes a processor coupled to a memory, one or more forwarding tables residing within the memory, and one or more ports. The ports are associated with a plurality of virtual local area networks and a plurality of bridge domains. Each of the bridge domains is associated with one of the forwarding tables, and each of the forwarding tables is associated with one of the bridge domains. The processor is configured to assign a first tag to a received packet, assign a second tag to the received packet, look up the destination address of the received packet in one of the forwarding tables, and selectively flood the ports of the active bridge domain with a copy of the received packet. The active bridge domain includes one of the plurality of bridge domains. The active bridge domain is associated with the ingress port of the received packet.
