These examples are not comprehensivedirections. They are intended to give you some guidance with typical configurations.To support your own IP addresses, interfaces, names, and so on, you can copy and paste from these examples to your CLI. Be sure that youmake the necessary changes.The following illustration shows the configurations described on the following examples. These configurations show how to create BGPareas using physical and virtual links. They include setting up the interfaces and peers groups with each other.Figure 27.
