bgp configuration lab using cisco packet tracer


In this article I am going to show you how to configure bgp step by step.This is a bgp configuration example lab showing bgp configuration using cisco packet tracer.I will show you how to configure bgp routing protocols on cisco router using three router.This is an example lab showing bgp configuration.Here in This Lab I have taken  3 AS they are 1,71 and 79 respectively

BGP neighbors can be of two types:


  • IBGP neighbors – when two neighbors are in the same AS(Autonomous System);

  • EBGP neighbors – when two neighbors belong to different AS(Autonomous System).

Step 1:Draw BGP Topology Diagram.

Step 2: Assign ip address on each device as mentioned in Diagram.

Step 3: bgp configuration on Router R1:


 

R1(config)#router bgp 1


R1(config-router)#neighbor 172.16.0.2 remote-as 71


R1(config-router)#network 10.0.0.0 mask 255.0.0.0


R1(config-router)#exit


R1(config)#do write


Building configuration...

[OK]


R1(config)#

Step 4: bgp configuration on Router R2:


 

R2(config)#router bgp 71


R2(config-router)#neighbor 172.16.0.1 remote-as 1



R2(config-router)#neighbor 172.14.0.2 remote-as 79


R2(config-router)#network 40.0.0.0 mask 255.0.0.0


R2(config-router)#exit


R2(config)#do write


Building configuration...

[OK]


R2(config)#

Step 5:  bgp configuration on Router R3:


 

R3(config)#router bgp 79


R3(config-router)#neighbor 172.14.0.1 remote-as 71
R3(config-router)#network 40.0.0.0 mask 255.0.0.0


R3(config-router)#exit


R3(config)#do write


Building configuration...

[OK]


R3(config)#

Step 6: bgp configuration Testing and troubleshooting.


 

For bgp testing we will ping both pc and check the network communication.


Now I am on PC2:


 

PC>ipconfig



PC>ping 10.0.0.2

 

Step 7: check bgp route on router R1:


R1#show ip route

Step 8: Check whether bgp protocols configure or not on Routre R1:


 

R1#show ip protocols

Step 9: Show BGP Status


R1#show ip bgp summary

 

Show bgp neighbors status:


 

R1#show ip bgp neighbors






 

Similarly we check bgp route on Router R2:

 

R2#show ip route

 

 

 

R2#show ip protocols

 

Similarly check bgp route on Router R3:

 

R3#show ip route

 

R3#show ip protocols
