Enabling BGP Routing

To enable BGP routing, you establish a BGP routing process and define the local network. Because BGP
must completely recognize the relationships with its neighbors, you must also specify a BGP neighbor.
BGP supports two kinds of neighbors: internal and external. Internal neighbors are in the same AS;
external neighbors are in different autonomous systems. External neighbors are usually adjacent to each
other and share a subnet, but internal neighbors can be anywhere in the same AS.
