Hi all ,
i will start to fill in the forum a lot of diagrams that i will build it and we can discuss it .
if this step is good and the administratot will not disagree i continue it.

Here is the configuration :


R1(config) # router bgp 100
R1(config-router) # Bgp log-neighbor-changes
R1(config-router) # Neighbor remote-as 200
R1(config-router) # Network mask


R2(config) # router bgp 200
R2(config-router) # Bgp log-neighbor-changes
R2(config-router) # Neighbor remote-as 100
