Patent ID: 8654769

Claim:
A method for convergence of multicast traffic in response to a topology change, said method comprising: in response to a change in a multicast topology, receiving multicast traffic at a network device; determining, by the network device, a querier status of said network device; in response to a determination by the network device that the network device is to act as a querier, flooding, during a first time interval, said received multicast traffic to a group of receivers through an interface of said network device to facilitate a convergence of said received multicast traffic; and in response to a determination by the network device that the network device is to act as a non-querier, flooding, during a second time interval, said received multicast traffic to the group of receivers through the interface of said network device to facilitate the convergence of said received multicast traffic, wherein the second time interval is different from the first time interval.
