Setting Up the Lab
Feel free to use any combination of routers as long as you fulfill the topology diagram as shown in Figure 4-1. It is not compulsory to use the same model of routers, but this will make life easier should you like to load configurations directly from the CD-ROM into your own devices.

If you have a mix of 10- and 100-Mbps Ethernet interfaces, adjust the bandwidth statements on the relevant interfaces to keep all interface speeds common. This will ensure that you do not get unwanted behavior because of differing IGP metrics.
From now on, you will find some routers using ...
