1 Introduction

This document explains how to build a testbed on a group of computers for test several implementations of macrobility (Mobile IP, IPv4 and IPv6) and micromobility (Cellular IP, IPv4 and IPv6).

The next figure shows the testbed:

The goal of this scheme is to be able to have the maximum number of networks using the minimum number of computers. We have five computers and five networks. Only one computer is connected to the Internet. This computer uses ProxyARP and the rest of computers can access to Internet across this PC.

The IP addresses in the networks are divided in two parts:

• 29 bits for the network address, and
• 5 bits for the computer address

This configuration allows us to have six computers in every network (althoug we don't use all of them).
