Abstract
A network component comprising a processor configured to implement a method comprising receiving a multicast listening state (MLS) report comprising a multicast state data from a mobile node (MN), sending the multicast state data to an access router (AR), establishing a tunnel with the AR, and forwarding at least one multicast data stream associated with the multicast state data to the AR via the tunnel. Also disclosed is an AR configured to implement a method comprising receiving a multicast state data for a MN, evaluating the multicast state data, indicating whether the multicast state data is supported by the AR, establishing a tunnel with a second AR, and receiving at least one multicast data stream associated with the multicast state data from the second AR via the tunnel.
