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
