Abstract
This document introduces extensions to Mobile IPv6 and IPv6 Neighbour
Discovery to allow for local mobility handling. Hierarchical
mobility management for Mobile IPv6 is designed to reduce the amount
of signalling between the Mobile Node, its Correspondent Nodes, and
its Home Agent. The Mobility Anchor Point (MAP) described in this
document can also be used to improve the performance of Mobile IPv6
in terms of handover speed.

1. Introduction
This memo introduces the concept of a Hierarchical Mobile IPv6
network, utilising a new node called the Mobility Anchor Point (MAP).
Mobile IPv6 [1] allows nodes to move within the Internet topology
while maintaining reachability and on-going connections between
mobile and correspondent nodes. To do this a mobile node sends
Binding Updates (BUs) to its Home Agent (HA) and all Correspondent
Nodes (CNs) it communicates with, every time it moves.
Authenticating binding updates requires approximately 1.5 round-trip
