            Prefix Delegation Support for Proxy Mobile IPv6

Abstract

   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.
