This chapter presented a pedantic Mobile IP example as a learning tool and highlighted the major concepts of IOS Mobile IP configuration in a simple lab topology. We introduced IOS configuration commands and looked at basic configuration of the Home Agent, FA, and Mobile Node. We considered common troubleshooting areas on the different Mobile IP entities, and we showed how to evaluate the proper functioning of the Mobile IP process.
The remaining chapters build on the basic understanding of the protocol from Chapters 2 and 3—and the hands-on configuration in this chapter—to help build real-world solutions. Applying Mobile IP to real-world deployments enables a good understanding of the benefits and implications of Mobile IP. The solutions are broken down by the size of the roaming area and the client options.
