            Prefix Delegation Support for Proxy Mobile IPv6
                      draft-ietf-netext-pd-pmip-08

Abstract

   This specification defines extensions to Proxy Mobile IPv6 protocol
   for allowing a mobile router in a Proxy Mobile IPv6 domain to obtain
   delegated IP prefixes for its attached mobile networks.  The mobility
   entities in the network will provide network-based mobility
   management support for those delegated IP prefixes just as how IP
   mobility support is provided for the mobile node's home address.
   Even as the mobile router performs an 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.
