Perhaps an easier way to force the opposite peer to become the tcp server in
regards to the bgp, less margin for error this way:
router bgp 300
!
no synchronization
bgp log-neighbor-changes
neighbor 192.168.12.2 remote-as 200
neighbor 192.168.12.2 transport connection-mode passive <---------
no auto-summary
This can also be done in a peer session template versus per neighbor.
