In the previous chapter, we learned about the basics pertaining to Border Gateway Protocol, which included design considerations, protocol characteristics, and attributes, and then concluded the chapter by learning how to establish both internal and external BGP neighbor adjacencies and advertise routes using BGP.
This chapter expands on the fundamentals described in the previous chapter and, taking this one step further, delves into detail on path control using BGP, and other advanced BGP implementations, such as route reflectors and confederations. The core ROUTE exam objective covered in this chapter is:
- Implement an eBGP based solution, given a network design and a set of requirements

- Border Gateway Protocol Path Control Overview
