Abstract:
In a network comprising a first subnet comprising a first WLAN associated with a home wireless switch a second subnet comprising a second WLAN associated with a first current wireless switch and a third subnet comprising a third WLAN associated with a second current wireless switch, methods are provided for forwarding a Broadcast/Multicast (BCMC) packet generated by a first wireless client device when the first wireless client device roams from the first subnet to the second subnet and a second wireless device roams from the first subnet to the third subnet. Other methods are provided for forwarding a BCMC packet generated by a wired host to a first wireless client device when the first wireless client device roams from the first subnet to the second subnet and to a second wireless device when the second wireless device roams from the first subnet to the third subnet.
