This is not a bug. You are looking at the wrong thing. The "connect-retry" timer is only used when a connection attempt failed (connect(2) failure or similar). You hit the IdleHold timer here because the session is opened and a NOTIFICATION is sent back. This results in exponential backoff of the connection and there the largest possible value is 3600 seconds. > >How-To-Repeat: > bgps# cat /etc/bgpd.conf | fgrep connect-retry > connect-retry 300 >
