Yep... think about it... the v6 routing protocols use it for next hop, and
you could have two v6 global unicast addresses on each side of a p2p link
that are in different subnets, and it *should* still work (haven't gotten a
chance to lab it yet), because it uses link locals for communication - it
took me a little while to get used to that... :)
