Can you outline such a case. It's not the simple use of Mobile IP
noted below as for that router prefix autoconfiguration is sufficient.

This is an important point.  The functionality needed by
a host in order to connect to network depends on the
functionality provided by the router that offers the
netwok prefix.

Check.

Well, there are such cases, and they should be allowed.
