                Prefix Delegation for Proxy Mobile IPv6
                    draft-ietf-netext-pd-pmip-01.txt

Abstract

   DHCPv6 Prefix Delegation can be used to assign a prefix or prefixes
   to a mobile router for use on the links in the mobile network as
   specified in [RFC6276] but not supported in Proxy Mobile IPv6.  This
   document specifies an extension to Proxy Mobile IPv6 protocol for
   supporting network mobility using DHCPv6-based Prefix Delegation.

1.  Introduction

   DHCPv6 Prefix Delegation [RFC3633] (DHCPv6-PD) can be used to assign
   mobile network prefix(es) to a mobile router (MR) as specified in
   DHCPv6 Prefix Delegation for Network Mobility (NEMO) [RFC6276].
   However, there is a gap currently for this NEMO support in Proxy
