Abstract:
1. A method, comprising: detecting a host device on a port of a first forwarder switch in a network; detecting a movement of the host device from the first forwarder switch to a second forwarder switch; and in response to the movement of the host device, multicasting updated device information for the host device that includes at least one address of the host device to a plurality of switches of a convergence group of a subgroup within the network and a plurality of switches of a proximity group of the subgroup, without forwarding the updated device information for the host device to one or more other forwarder switches of the subgroup that are not members of the proximity group and without forwarding the updated device information for the host device to other subgroups within the network, wherein the convergence group includes core switches in the network, that are not configured as forwarder switches of the subgroup but that provide a path between forwarder switches of the subgroup and the other subgroups within the network, and wherein the proximity group includes forwarder switches of the subgroup that are grouped together based on radio proximity.
