Abstract
A first network device in a network is provided. During operation, the first network device can elect the first network device as a designated forwarder (DF) of multicast traffic in a subnet for a Rendezvous Point (RP) of a multicast group. Here, the first network device can operate in conjunction with a second network device as a virtual gateway device of the subnet. The second network device can be elected as another DF for the RP. The first network device can determine whether the first network device is elected as a forwarding device based on a selection parameter. Upon determining that the first network device is elected as the forwarding device, the first network device can program, in the forwarding hardware, a forwarding entry for forwarding the multicast traffic. The first network device can then forward multicast traffic associated with the multicast group based on the forwarding entry.
