                Prefix Delegation for Proxy Mobile IPv6
                      draft-ietf-netext-pd-pmip-03

Abstract

   Proxy Mobile IPv6 enables IP mobility for a host without requiring
   its participation in any mobility signaling, being the network
   responsible for managing IP mobility on behalf of the host.  However,
   Proxy Mobile IPv6 does not support assigning a prefix to a router and
   managing its IP mobility.  This document specifies an extension to
   Proxy Mobile IPv6 protocol for supporting network mobility using
   DHCPv6-based Prefix Delegation.
