The problem is that other hosts will clear their destination caches if they
receive a NA without the router bit set. So a host trying to communicate 
with an address taken from the prefix will constantly go back to the default
router, get a redirect, do a neighbor discovery probe and clear the
destination cache for that address.

Maybe all nodes that receive a prefix using PD have to behave as routers for the
purposes of (at least) ND.
