That’s it! Pretty simple. Now let’s verify our configuration.

Verifying EBGP

We’ll use the following commands to verify our little EBGP network.

 

■

show ip bgp summary

 

■

show ip bgp 

 

■

show ip bgp neighbors

The show ip bgp summary Command

The 

show ip bgp summary

 command gives you an overview of the BGP status. Each 

configured neighbor is listed in the output of the command. The output will display the 

IP address and AS number of the neighbor, along with the status of the session. You can 

use this information to verify that BGP sessions are up and established, or to verify the IP 

address and AS number of the configured BGP neighbor.
