Abstract

   This paper documents some of the usage patterns and the associated
   issues when deploying a Home Network for Network Mobility (NEMO)-
   enabled Mobile Routers, conforming to the NEMO Basic Support.  The
   aim here is specifically to provide some examples of organization of
   the Home Network, as they were discussed in NEMO-related mailing
   lists.

1.  Introduction

   This document assumes that the reader is familiar with IPv6 Mobility
   as defined by Mobile IPv6 and the Network Mobility (NEMO) Basic
   Support.  In order to read this document properly, it is important to
   realize that in NEMO, the Home Network can encompass much more than
   the Home Link, as it spans the Home Link and all the Links that the
   Mobile Routers (MRs) carry with them.  Exactly how the two concepts
   relate in a given deployment depends on the organization of the Home
   Network, as described below.

   Five different organizations of the Home Network including a
   hierarchical construction are documented:

   MIPv6 Home Network:  A short reminder of what the Home Network is
      with Mobile IP, in order to help the reader figure out the
      evolution toward NEMO.

   NEMO Extended Home Network:  In this arrangement, the Home Network is
      only one subnet of a larger aggregation that encompasses the
      Mobile Networks, called Extended Home Network.  When at home, a
