A general MIPv6 testbed would consist of:

• at least one Home Agent
• at least one Mobile Node
• at least one Correspondent Node
• several (>=2) IPv6 networks

At least one of the IPv6 networks must contain a Home Agent. Ideally, another two IPv6 networks should allow for the location of a Mobile Node (when away from home) and a Correspondent Node respectively. A very simple MIPv6 testbed like this is illustrated in Figure 10-5.

The example in the figure shows three networks although, in theory, two networks would suffice (the Correspondent Node could be located in Network 1 or 2).
