Abstract
A mobile node needs at least the following information: a home
address, a home agent address, and a security association with home
agent to register with the home agent. The process of obtaining this
information is called bootstrapping. This document discusses issues
involved with how the mobile node can be bootstrapped for Mobile IPv6
(MIPv6) and various potential deployment scenarios for mobile node
bootstrapping.

1. Introduction
Mobile IPv6 [RFC3775] specifies mobility support based on the
assumption that a mobile node (MN) has a trust relationship with an
entity called the home agent. Once the home agent address has been
learned (for example, via manual configuration, anycast discovery
mechanisms, or DNS lookup), Mobile IPv6 signaling messages between
the mobile node and the home agent are secured with IPsec or with the
authentication protocol, as defined in [RFC4285]. The requirements
for this security architecture are created with [RFC3775], and the
details of this procedure are described in [RFC3776].
In [RFC3775], there is an implicit requirement that the MN be
provisioned with enough information that will permit it to register
successfully with its home agent. However, having this information
statically provisioned creates practical deployment issues.
This document serves to define the problem of bootstrapping.
Bootstrapping is defined as the process of obtaining enough
information at the mobile node that it can successfully register with
an appropriate home agent.
The requirements for bootstrapping could consider various
scenarios/network deployment issues. It is the basic assumption of
this document that certain minimal parameters (seed information) are
available to the mobile node to aid in bootstrapping. The exact seed
information available differs depending on the deployment scenario.
This document describes various deployment scenarios and provides a
