Why do you care how a provider does X?
Your requirement doesn't seem to be run loose-uRPF in cores, although that
may be one way a provider chooses to solve the problem. You requirement
is "not get bogon sourced traffic on your link."
I know its tempting to tell other people how to run their networks. But
specifying the solution sometimes cuts out alternative solutions which
work just as well or maybe better.
