Note that RA=high will only solve part of the problem; it does not
affect address selection at all, only the routing table decisions. So
if you have a rogue RA with a bogus prefix, the end clients can
happily try to connect through _your_ gateway (since RA=high) using
_their_ prefix, which will probably break.
