If I understand correctly, what you want is the same as conditional advertisements:

except that it needs to be applied to received routes instead of advertised routes.

In other words, it's not enough for you to dump the bogon traffic in a blackhole; you also want to dump bogonish routes received from your peers before they even get to your RIB.

If I understood it right, a na�ve look at it would be that since the function already exists in the other direction it should not be too big of a deal to do it the other way, but I'm not the one compiling IOS.
