Summary

This case study showed you the use of the many VPN features discussed in this book. This is by no means the only possible solution to the given scenario; however, the goal of this chapter was to show you how to implement Cisco VPN features in an integrated fashion. As you will learn, each networking situation has its own set of unique problems and issues and its own set of possible solutions.

A Last Bit of Advice As you can see from this case study, even though the network is medium-sized, the configuration is quite involved. Therefore, I would highly recommend that you implement one VPN component at a time, making the setup and troubleshooting process easier. For example, I would probably set up the L2L DMVPN configuration first, and then focus on the remote access. And as a final note in this book, VPNs are probably one of the most complicated technologies you'll deal with in the security field. I've learned a long time ago that I don't know everything and am always being introduced to problems I've never seen before. Therefore, having a very good foundation in the understanding of VPNs is very important (I can't stress this last point enough), which is why the first part of the book was devoted to VPN technologies and why each part of the book contained a troubleshooting chapter. With a good foundation, you should be able to design a solid, secure VPN solution and troubleshoot any problems that may crop up. And last, good luck with your VPN endeavors! Cheers!
