This is what I'd do (and have done before) to even things out. Some would
argue that when prepending received routes in a route-map, you should
prepend with your own ASN. I've found it less confusing to prepend that
provider's ASN. AFAIK, either works, and the latter certainly does as
it's what I've done.
