I've been told that Linux does not honor ND requests with off-link
addresses.  I don't know how this interacts with tunneling.

This vulnerability is different from ARP spoofing because it allows
you to install arbitrary /128s into the node's routing table.  ARP
spoofing is confined to adresses on the same subnet.
