Need provider suggestions - BGP transit over GRE tunnel

[jack at crepinc.com (Jack Carrozzo)]

The general way this works for a small shop is two transits - one cheap
provider who you move most of your bits over, and one more expensive but
reliable link. Prepend / localpref / whathaveyou to your hearts content
until pleased with your bandwidth bill, and when your cheap link toasts
you're all set.

What you're suggesting with the GRE over commodity links would *work*, but:

(a) By the time you convince a network that they should do this for you,
you're likely going to be out as much money as just brining up directly
connected transit and not pushing much traffic at them.

(b) You're using the GRE setup as your backup... over a setup thats about
100x less reliable than your primary link.
