Abstract
A method and system for efficiently handling multicast packets by aggregating VLAN (virtual local area network) context. In one embodiment, multicast registration information is received for a first client in one VLAN and then multicast registration information for the second client in a second VLAN. An aggregated list is created of the multicast registration information for the first client and the second client. In this embodiment, the aggregated list of the multicast registration information is forwarded for the first client and the second client to a second intermediate device. Then, when handling a multicast packet at the second intermediate device, the present invention accesses the aggregated list of the multicast registration information for the first client and the second client. As a result, the present invention allows the second intermediate device to perceive having only a single VLAN registered to receive the multicast packet.
