Abstract
This document describes the Network Mobility (NEMO) Basic Support
protocol that enables Mobile Networks to attach to different points
in the Internet. The protocol is an extension of Mobile IPv6 and
allows session continuity for every node in the Mobile Network as the
network moves. It also allows every node in the Mobile Network to be
reachable while moving around. The Mobile Router, which connects the
network to the Internet, runs the NEMO Basic Support protocol with
its Home Agent. The protocol is designed so that network mobility is
transparent to the nodes inside the Mobile Network.
