Hi, Guys!

I did some research to identify how state of TCP connection
corresponds to BGP peer state. I configured one neighbour as Active,
and the other as Passive and started to play with debug & ACL.  I
managed (by blocking ACK packets, OPEN packets)  to identify that
correspondence. You wont find this info in CCIE books, actually they
have either incorrect info, or not based on Cisco implementation.

So here it is:

BTW, Cisco does not show "Connect" state in output of the "sh ip bgp
sum" but shows it in the "debug bgp all" output =) .

You questions and feedback are highly welcome! I am ready to proof my
research =).
