Abstract
A method of routing multicast traffic, suitable for use in a network comprising a router node connected to a first data network and to a second data network, the router node having a capability to route multicast traffic from the first and second data networks to a user equipment, is provided. The method comprises: receiving a first message from the user equipment at the router node, the first message requesting membership of a first multicast group having a first multicast address; and inhibiting receipt of multicast traffic having the first multicast address from at least the second data network by the user equipment, dependent upon a determination as to whether the first message may relate to a multicast address in the first network.
