Hello everybody.
I am setting up OpenBGP for the first time in replacement to Cisco.
However, I am having some troubles which I could not realize the
reason myself, so I

I have lowered holdtime and holdtime min just for testing purposes.
Here is the relevant Cisco config

The problem I get is:
neighbor 200.184.196.18 (Intelig): state change Connect -> OpenSent,
reason: Connection opened
neighbor 200.184.196.18 (Intelig): state change OpenSent -> Active,
reason: Connection closed
# bgpctl sh nei Intelig timers
BGP neighbor is 200.184.196.18, remote AS 17379
