It seems in such a case, the traffic still doesn’t know where to go, but you don’t realize it because you have a default.
Then you pass the traffic to one of the providers who doesn’t have a route for it and they drop it instead of you. If you see something different, then, by definition, said provider is not feeding you a full set of their tables, or, they, too, are depending on a default and are not receiving a full set of tables.
