BGP Neighbor Configuration: Example

The following example shows how BGP neighbors on an autonomous system are configured to share
information. In the example, a BGP router is assigned to autonomous system 109, and two networks are listed
as originating in the autonomous system. Then the addresses of three remote routers (and their autonomous
systems) are listed. The router being configured shares information about networks 172 .16 .0.0 and 192.168
.7.0 with the neighbor routers. The first router listed is in a different autonomous system; the second neighbor
and remote-as commands specify an internal neighbor (with the same autonomous system number) at address
172 .26 .234.2; and the third neighbor and remote-as commands specify a neighbor on a different autonomous
system.
