DHCPv6 Prefix Delegation for Network Mobility (NEMO)
Abstract
One aspect of network mobility support is the assignment of a prefix
or prefixes to a mobile router for use on the links in the mobile
network. This document specifies how DHCPv6 prefix delegation can be
used for this configuration task. The mobile router plays the role
of requesting router, while the home agent assumes the role of
delegating router. When the mobile router is outside its home
network, the mobile router also assumes the role of DHCPv6 relay
agent, co-located with the requesting router function.

1. Introduction
One aspect of network mobility support is the assignment of a prefix
or prefixes to a mobile router for use on the links in Network
Mobility (NEMO). DHCPv6 prefix delegation (DHCPv6PD) [RFC3633] can
be used for this configuration task.
The model of operation of DHCPv6PD for prefix delegation is as
follows [RFC3633]. A delegating router is provided IPv6 prefixes to
be delegated to requesting routers. A requesting router requests
prefix(es) from the delegating router. The delegating router chooses
prefix(es) for delegation, and responds with prefix(es) to the
requesting router. The requesting router is then responsible for the
delegated prefix(es). Note that DHCPv6 options for prefix delegation
defined in [RFC3633] have been defined for general use across
routers, and not only for mobile routers running the NEMO Basic
Support protocol [RFC3963].
