Application Example
The following simple network using EBGP and IBGP will demonstrate some of the basic BGP setup
commands discussed previously:
AS 200
BGP Speaker 1
40.0.0.1/24
10.0.0.1/24
20.0.0.1/24
In the above network, Speakers 1, 2, and 3 are part of AS 100 and are fully meshed. Speaker 4 is in AS
200 and Speaker 5 is in AS 300.
AS 100
BGP Speaker 1
Assign the speaker to AS 100:
-> ip bgp autonomous-system 100
Peer with the other speakers in AS 100 (for internal BGP, and to create a fully meshed BGP network):
-> ip bgp neighbor 20.0.0.2
-> ip bgp neighbor 20.0.0.2 remote-as 100
-> ip bgp neighbor 20.0.0.2 admin-state enable
-> ip bgp neighbor 10.0.0.2
-> ip bgp neighbor 10.0.0.2 remote-as 100
-> ip bgp neighbor 10.0.0.2 admin-state enable
Peer with the external speaker in AS 200 (for external BGP):
-> ip bgp neighbor 40.0.0.2
-> ip bgp neighbor 40.0.0.2 remote-as 200
-> ip bgp neighbor 40.0.0.2 admin-state enable
