The Example Network

It’s easier to follow a theoretical discussion if there is a real world example thrown into the mix. For this purpose, I have added a sample network that you can refer back to throughout Linux Routing.

The Internet is one huge IP network. As you probably already know, every machine on such a network has its own IP address in the format, xxx.xxx.xxx.xxx, except in cases where private addressing schemes are used, such as 192.168.xxx.xxx and 10.xxx.xxx.xxx. However, the entire Internet is a bit large to use in the discussion here. Instead, I’ll define a smaller network set to work with while learning how specific routing protocols work. I will then use this same example network in the chapters where things are actually set up. ...
