Proxy Mobile IPv6 [RFC5213] enables network-based mobility management support for an IP host without requiring its participation in any IP mobility signaling. In Proxy Mobile IPv6 (PMIPv6), the mobile access gateway (MAG) performs the mobility management function on behalf of the mobile node (MN). The local mobility anchor (LMA) is the home agent for the MN and the topological anchor point. The mobility elements (LMA and MAGs) in the network allow an IP host to obtain an IPv4 address and/or a set of IPv6 addresses and be able to obtain IP mobility support for those IP address(es) within the Proxy Mobile IPv6 domain. In this context, the mobility management support is enabled for an individual IP host, which is the mobile node. The IPv4 home address or the IPv6 home network prefixes are logically bound to the link shared between the mobile access gateway and the mobile node, and only the mobile node can use those IP address(es) by configuring them on the interface attached to that link. Currently, there is no mobility support for the mobile networks attached to a mobile router (MR) in a Proxy Mobile IPv6 domain.

             Prefix Delegation Support for Proxy Mobile IPv6


   This specification defines extensions to the Proxy Mobile IPv6    protocol for allowing a mobile router in a Proxy Mobile IPv6 domain    to obtain IP prefixes for its attached mobile networks using DHCPv6    prefix delegation.  Network-based mobility management support is    provided for those delegated IP prefixes just as it is provided for    the mobile node's home address.  Even if the mobile router performs a    handoff and changes its network point of attachment, mobility support    is ensured for all the delegated IP prefixes and for all the IP nodes    in the mobile network that use IP address configuration from those    delegated IP prefixes.
