What kind of error did you get?

If complete garbage came back, I'm not sure what the resolver does with
that (oddly enough, I never tested that)

The more usual case is you get a proper DNS result of NXDOMAIN which
indicates the query is valid, but the entry is not in DNS. It's
pointless trying another cache as per DNS, they should all then return
that result.

This is why the router did not try the other entries in resolv.conf -
that usually only happens when a cache does not respond. So the
behaviour you saw is probably correct albeit not the behaviour you wanted.
