Abstract
A network device operating as a tunnel endpoint in an overlay network is provided. During operation, the network device can receive a multi-destination packet associated with a virtual local area network (VLAN) via an edge port of the network device. The network device can determine a multicast group assigned for distributing multi-destination traffic of the VLAN from a data structure in forwarding hardware of the network device. The network device can then forward the multi-destination packet via a root-path multicast tree associated with the multicast group. Subsequently, the network device can receive forwarding information shared by a second network device of the overlay network based on a control packet sent by the second network device. The network device can then program, in the forwarding hardware, a shortest-path multicast tree associated with the multicast group, wherein the shortest-path multicast tree is for distributing traffic belonging to the VLAN.
