HOW TO eBGP WITH MULTIHOP COMMAND
 
Interface IP Address Configuration 
 
R1 
 
Interface  IP Address   Subnet Mask 
S 0/2/0    1.1.1.1            255.0.0.0 
E 0          10.1.1.1         255.0.0.0 
 
R2 
 
Interface  IP Address   Subnet Mask 
S 0           1.1.1.2           255.0.0.0 
E 0            20.1.1.1        255.0.0.0 
 
Task 1 : 
 
Configure a BGP neighbor relationship between R1 and R2. R1 should be configured in 
AS 100 and R2 should be in AS 200. Establish the neighbor relationship between peers  
that are not directly connected. You are allowed to create a static route on each router to 
accomplish this task.
 
R1 
 
Ip route 20.1.1.1 255.0.0.0 1.1.1.2 
 
Router bgp 100 
Network 1.0.0.0 
Neighbor 20.1.1.1 remote-as 200 
Neighbor 20.1.1.1 ebgp-multihop 
No synchronization 
 
R2 
 
Ip route 10.1.1.1 255.0.0.0 1.1.1.1 
 
Router bgp 200 
Network 1.0.0.0 
Neighbor 10.1.1.1 remote-as 100 
Neighbor 10.1.1.1 ebgp-multihop 
No synchronization 
 
Verification: 
 
R1#show ip bgp summary 
 
The output displays neighborship as established.
