Ex2 Chapter 12 – BGP basics

The Border Gateway Protocol (BGP) is the core routing protocol of the Internet. It maintains a table of IP networks or 'prefixes' which designate network reachability among autonomous systems (AS). It is described as a path vector protocol. BGP does not use traditional Interior Gateway Protocol (IGP) metrics, but makes routing decisions based on path, network policies and/or rulesets.

Routers use “routing protocols” to exchange routing information with each other.

Static and Dynamic Routing
Routers know of networks that are only directly connected to them.  Obviously, routers need some method of learning about distant networks they need to access.  There are two methods of learning about these distant networks, static and dynamic route learning. Static routes are when an administrator adds specific network routes to a router or multiple routers.
