Task 1 
 
Configure a BGP neighbor relationship between R1, R2 and R3. R1 should be in AS 200, 
R2 should be in AS 100 and R3 should be in AS 200.

Verification: 
 
R1#show ip bgp summary
 
The output displays that BGP neighbors have established a TCP connection.
 
R1#show ip route 
 
The output states that the BGP routes denoted as ‘B’ in the routing table. 
 
R1#show ip bgp
 
The output displays the BGP table.
