n Chapter 7, "BGP's Basic Components," we talked about BGP
and what it was used for, and we maintained a focus on the path attributes that are used in BGP. In this chapter, we will step into the basic configuration of BGP. I say basic because Chapter 9, "BGP Scalability and Advanced Fea- tures," will focus on more advanced configurations, scaling, and other important properties of BGP.
The process of configuring BGP routing is much more complex than set-
ting up any of Cisco's supported interior routing protocols. Using BGP, we must configure both interior and exterior protocols. Obviously, this will involve additional configuration steps to establish a routing process and indicate which networks can be advertised to other networks.
efore the configuration process for BGP can begin, we need to deter-
mine some basic information. Table 8.1 contains important BGP router checklist information. You can refer to this information whenever you need to configure BGP.
