Final Words

Overall, we have developed Optimal Routing Design to be read, not just used as a reference. We strongly believe that understanding network design with all the available protocols makes you a better network engineer. Learning how to deploy multiple protocols, even if you will never use them, helps you to understand and apply the underlying principles and find techniques to work around problems that you might encounter.

We hope that you find the time spent reading our little missive to be well spent—and we expect to welcome you on the list of excellent network designers! So, kick back, put your feet on your desk, and read through from the front to the back. You can tell your boss you are learning how to design your network to scale.
