The Border Gateway Protocol (BGP) allows us to connect to systems around the globe. In this chapter, we will be looking at BGP, specifically the External Border Gateway Protocol (eBGP). To cover BGP in its entirety would take a book of its own. So, we will briefly cover BGP overall and then compare iBGP and eBGP to understand their differences. We will configure BGP, and by doing so, you will see how huge and powerful this protocol is.
Topics that will be covered in the chapter include the following:
- A brief history of BGP
- Comparing BGP to EGP and OSPF
- Configuring iBGP
- Configuring eBGP
- Verifying BGP
