Situation: 2 router setup a bgp adjacency (ibgp or ebgp).
Both router try to start the tcp session first. One will win and I think the
other tcp session die.
How I can controll this which will win?
These situation is interessting, when you form a peering and you have
a AS mismatch and you want force your "foreign" router sent the
(wrong)AS-number, instead
you sent your AS and the foreign will give you only the answer that there is
a AS mismatch.
Check this: R8(AS11=000B) and R7(AS7)
R8#
%BGP-3-NOTIFICATION: received from neighbor 150.50.7.7 2/2 (peer in wrong AS)
2 bytes 000B
R8#
R7#
%BGP-3-NOTIFICATION: sent to neighbor 150.50.8.8 2/2 (peer in wrong AS) 2
bytes 000B
R7#
In this case R7 detect the AS-mismatch and send a message.
How I could force R8 to do that?
thnx
Oliver
