Abstract:
A method of forwarding a multicast data packet in a network, comprising the steps of:(1) receiving the multicast data packet at a network access device; (2) determining whether the multicast data packet is to be forwarded according to an administratively scoped destination or a physically scoped destination; (3) in response to determining that the multicast data packet is to be forwarded according to an administratively scoped destination, forwarding the multicast data packet to an administratively scoped destination; and (4) in response to determining that the multicast data packet is to be forwarded according to a physically scoped destination, encapsulating the multicast data packet into a unicast packet and forwarding the unicast data packet to a second network access device that is a physical neighbor of the network access device.
