Thankfully at this point, we manage all CPE of any clients who peer with
us, and so far, the clients advertise our own space back to us. I'll go
back to looking at adequate timer settings for my environment.
All it takes is a quick phone call to the client IT people to inform
them that a change will be made, and when they prefer I do it (in the
event something goes south). Also thankfully, I'm within a quick
walk/drive to these sites, which I've found to be a comfort during the
last year while I've walked the BGP learning curve (one of my clients in
particular leaves me with quite a few resources (fibre connections,
hardware) for me to *test* with between site-and-PoP ;)
Cheers, and thanks!
