You can't do it at top-level nor it's not practical to hope that some day BCP38 is done in reasonably many last-mile port.I don't know that that's true, actually; unicast-rpf does, as I understand it, most of the work, and is in most of the current firmware.
Even if all of last mile devices support uRPF, which it does not, getting all these 100s of millions of ports configured correctly does not strike as practical goal. Fixing 6000 non-stubby transit providers catering sufficiently small tails is much more practical goal. -- ++ytti
