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
