Summary
At this point in our journey, your network should be in much better shape. In this chapter, we accomplished quite a bit. We've discussed advanced topics such as routing, NAT, subnetting, Quality of Service, and we even set up redundancy for our DHCP and DNS servers. It would sure be a shame if something were to happen to our awesome network. That's why in the next chapter, I'll cover how to strengthen the security of our network. See you there!
