Re: EEM to keep BGP peer shut during an interface flap

Hi Mathew,
I haven't done too much within EEM, but I'm sure plenty of the other experts
here could lend some advice on that. If the main issue is to overcome the
flapping, I think trying to use a tracked object with a delay coming back up
is the path I'd investigate.
