Abstract
A system and method for delivering multicast/broadcast data frames, originating in a service virtual local area network (S-VLAN), to a plurality of locations on a customer network is disclosed. In one embodiment, a method for delivering multicast/broadcast data frames includes analyzing ingress data frames, including customer virtual local area network identifiers (C-VIDs) associated with one or more divisions within one of a plurality of locations assigned by a customer network, received via incoming ports of each Ethernet switch associated with one of the plurality of locations and learning the C-VIDs of the ingress data frames, storing the learnt C-VIDs in the Ethernet switch, and forwarding the multicast/broadcast data frames to the one or more of the plurality of locations, via one or more outgoing ports of one or more of multiple Ethernet switches associated with the plurality of locations, based on the learnt and stored C-VIDs by each Ethernet switch.
