A method, an apparatus, a system, and logic encoded in one or more computer-readable tangible medium to carry out a method. The method includes maintaining the state of clients of an access point controlled by a controller in the controller of the access point, including multicast group information, and updating the access point with multicast group identification for the clients, such that the controller in combination with the access point can forward packets, and such that multicast group information for a roaming client of the access point is maintained.
