Re: multi homing pressure

I thought SLAs existed to comfort nontechnical people into signing contracts, then denying credits via careful weasel words when the time comes for the customer to collect. Or maybe I'm just cynical.

Even a lowly 2500 can be loaded up with a carrier-assigned private ASN and fed a couple routes. (Maybe it's a little more complex when one needs equal-cost multipath, but it's still hardly rocket science.)
