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. -Jack Carrozzo
