A. one can always find different providers. If you are trying to build
something and you don't have the right tools then get new tools. If you
can't afford multiple redundant links between pieces of your own AS and
you want to use an upstream to provide this for you then you must pick a

If he would buy transit from *2* providers in 2 cities, he'd be fine, as
he could announce the longer prefixes the rest of the internet does not

Ralph,
I think you're missing the point a bit. Don't expecy to use resources on
other people's networks and routers to do your own traffic engineering
unless you pay them for it.
You must buy transit from the same ISP in each city, and then you can do
your traffic engineering using their r
