This is not my understanding of how ISATAP works on hosts.
Real autoconf is not performed, but rather you must configure your
system with a PRL (potential routers list) and these routers are
probed periodically in order to keep track of which of them are still
functioning and also to perform a sort-of unicast-only autoconf.
I am pretty sure that the person who added the ISATAP code created the
current behavior intentionally.
