In this chapter, we learned about the importance of choosing not only the type of routing you want to do, but also which routing protocol would be a best fit for your network. We found out that it all depends on your hardware and the size of your network and its design. We also learned how to configure EIGRPv6 and OSPFv3, which really was not as difficult as we thought it would be. But, you must always verify everything you do before you move on, step by step, and have a well-thought-out plan before you start making changes.
One very important command that we learned that we must configure, if you are going to be working in IPv6, is ipv6 unicast-routing. If you do not turn this on, you will not be able to route in IPv6 at all.
Next, get ready to attack Layer 2 switching.
