It may not be that simple. I guess I should have mentioned that I don't
route anything through Sprint. The only reason I've kept the Sprint circuit
is to avoid re-IP-ing. Sprint isn't reliable enough to carry customer
traffic. I do advertise the Sprint route, but I add a couple of hops to
make sure the traffic goes through my "real" circuit.
