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.
