Mobile IPv6 nodes often move to different subnets. If these nodes are members of a global multicast group, the home agent for that subnet must tunnel multicast packets for each of the mobile nodes separately to the new location for each node. Tunneling is done by encapsulating the multicast packet in an IPv6 header addressed to the mobile node's new location. This increases Internet traffic considerably if there are a large number of mobile nodes. This article describes a new mechanism of multicast tunneling for grouped IPv6 mobile nodes.
