I am looking for operational BCP feedback on common practice for tweaking down BGP holdtime/keepalive across GigE exchange points, since a peer could go down on the other side of the GigE switch without a corresponding adjacency change seen on your BR. The thought is to make down peers known as fast thru a GigE exchange as they would be over a POS private peer interface. The current defaults are pretty gross, and much worse than the ISIS hello and interface keepalive defaults of 10 seconds.
