My solution would be to filter the routes based on AS.

Someday, those routes will be announced from a valid provider, and you
will need to know the valid AS from which they should be announced to
ignore the bogons.

The RA knows?

Maybe this is a valid use of the RADB?

Cannot the NIC update the RA with both prefix and AS?
