Abstract
A first network device operating as a tunnel endpoint in a tunnel fabric is provided. During operation, the first network device can receive, via a local port, a network join request to receive multicast traffic of a multicast group from a second network device. The first network device can store a multicast state for the multicast group in a data structure associated with the control plane. The multicast state can indicate that the network join request is received via a tunnel between the first and second network devices. The first network device can then determine whether a source of the multicast group is coupled to the first network device. If the source is coupled to the first network device, it can program a multicast forwarding entry corresponding to the multicast state in forwarding hardware and forward the multicast traffic to the second network device based on the multicast forwarding entry.
