12. How to config BGP
(config)#router bgp <as-number> (config-router)#neighbor <ip-address> remote-as <neighbor as-number>

13. How to config BGP with dual links
(config)#router bgp <as-number> (config-router)#neighbor <ip address> update-source <ip address> (config-router)#neighbor <ip address> ebgp-multihop <ttl number> (config-router)#neighbor <ip address> remote-as <neighbor as-number> (config-router)#neighbor <ip address> password <string>

14. BGP neighbor states

15. BGP show commands
switch#show ip bgp switch#show ip bgp summary switch#show ip bgp neighbors (config-router)#network <prefix> mask <subnet mask>

16. Difference between iBGP and eBGP

17. BGP looping

18. How to config iBGP

19. BGP route filtering commands
(config-router)#neighbor <ip address> distribute-list <standard OR extended ACL) in/out
(config-router)#neighbor <ip address> prefix-list <name> in/out
(config-router)#neighbor <ip address> route-map <name> in/out
(config-router)#neighbor <ip address> filter-list in/out

20. BGP clear commands Switch#clear ip bgp*
Switch#clear ip bgp <neighbor-id>
Switch#clear ip bgp <neighbor-id> in
Switch#clear ip bgp <neighbor-id> soft in
Switch#clear ip bgp <neighbor-id> out
Switch#clear ip bgp <neighbor-id> soft out
Switch#clear ip bgp <neighbor-id> soft
Switch#clear ip bgp*soft
