Interactions between Proxy Mobile IPv6 (PMIPv6) and Mobile IPv6 (MIPv6):
                      Scenarios and Related Issues

Abstract

   The use of Proxy Mobile IPv6 (PMIPv6) and Mobile IPv6 (MIPv6) in the
   same network requires some care.  This document discusses scenarios
   where such mixed usage is appropriate and points out the need for
   interaction between the two mechanisms.  Solutions and
   recommendations to enable these scenarios are also described.

1.  Introduction

   Proxy Mobile IPv6 (PMIPv6) [RFC5213] is a network-based IP mobility
   protocol standardized by the IETF.  In some deployment scenarios,
   this protocol will be deployed together with Mobile IPv6 (MIPv6)
   [RFC6275], for example, with PMIPv6 as local mobility protocol and
   MIPv6 as global mobility protocol.  While the usage of a local
   mobility protocol should not have implications on how global mobility
   is managed, since PMIPv6 is partially based on MIPv6 signaling and
   data structure, some considerations are needed to understand how the
   protocols interact and how the different scenarios can be enabled.
