Hi All, I am testing BGP stability with extremely aggressive timers. The timers are 1/3. I see BGP flapping 2-3 times every 24 hours. Attached is a packet capture, captured on the system running bird. 10.194.8.11 is a Cisco ASR. 10.194.8.13 is the running bird instance. I see multiple keep-alives coming in from .11, but the bird instance responds with hold timer expired. This was about after 12 hours in established state. Connection opens right back up again. I don't see the same issue on upping the timers to 3/9 seconds. Anyone see anything like this before? Thanks, Saksham
