Abstract
A Mobile IPv6 node requires a home agent address, a home address, and
a security association with its home agent before it can start
utilizing Mobile IPv6. RFC 3775 requires that some or all of these
parameters be statically configured. Mobile IPv6 bootstrapping work
aims to make this information dynamically available to the mobile
node. An important aspect of the Mobile IPv6 bootstrapping solution
is to support interworking with existing Authentication,
Authorization, and Accounting (AAA) infrastructures. This document
describes MIPv6 bootstrapping using the Diameter Network Access
Server to home AAA server interface.

RFC 5447 Diameter MIPv6 NAS-to-HAAA Interaction February 2009
1. Introduction
The Mobile IPv6 (MIPv6) specification [RFC3775] requires a mobile
node (MN) to perform registration with a home agent (HA) with
information about its current point of attachment (care-of address).
The HA creates and maintains the binding between the MN's home
address and the MN's care-of address.
In order to register with an HA, the MN needs to know some
information, such as the home link prefix, the HA address, the home
