ABSTRACT:
Forwarding of multicast data frames over an Ethernet bridged network infrastructure is performed by storing in a bridge forwarding table the multicast destination address when the hosts are polled via the bridge by a router. Then when a multicast data frame is received by the bridge, the forwarding table is searched and the frame is forwarded to each port of the bridge that corresponds to a host that subscribed to the particular multicast session indicated by the multicast destination address.
