Your configuration looks like it should work. Assuming the router this configuration is going on will be directly connected to your transit provider you don't need "neighbor 216.XXX.XXX.8 ebgp-multihop 5." Multihop is only necessary for eBGP in special circumstances. You should re-evaluate the route-map. I'm not sure exactly what you are trying to accomplish, but this route-map is non-functional.
