He's asking why AT&T can't do the same thing Sprint was doing, as
they've disconnected Sprint and are using AT&T alone.
My answer: no reason they can't, beyond not wanting to or being really
dumb about it. Tell them you want them to advertise your netblock for
you because you don't need BGP. You don't have to; they can easily do
the routing and announcement for you. If they don't get it easily...
well, I'd go back to Sprint, because you'll probably have severe
problems later when someone updates something, breaks it and you're down
for a week before you can get through to anyone who will listen to your
unsupported (to them) setup. I was in the same situation years ago with
an Eschelon/ATG circuit: they simply didn't get how to work BGP with a
multihomed customer. I could convince them to fix it each time, but then
it'd break 4 months later. After the 4th time they screwed up, I dumped
them and gladly paid more for anyone else so it would actually work.
