Introduction to BGP
BGP is running in thousands of networks, almost as many as OSPF. When it runs, it relies heavily on the other IP routing protocols in use in the network, specifically the IGP. The main purpose of this section is to help you understand exactly how BGP relies on OSPF, and how OSPF supports and augments BGP operations and features.
To better set your expectations of this discussion of BGP, this section covers the points that aid in understanding this technology and how it interacts with OSPF. Clearly, there is much more information to impart on BGP, but that is beyond the scope of this book. I recommend that you consider BGP4 Inter-Domain Routing in the Internet by John Stewart.
