The main point is that I have two routers that are sitting right next to each other and have point-to-point connections to each other. And I have the IP addressing that we used in our demo. I'll show you that by, on Router1, I'm going to type, sh ip int e0/0. And, if you take a look at the top of the screen, right below where the routers are, you'll see that the internet address is 172.16.5.1/21, just like our example.
