matsuzaki-san's preso, i think the copy he will present next week at apops:

He (she?) says packets will ping-pong across the link if they are addressed to an address on the p2p subnet that isn't used. However, this is only true if there is no address resolution on the subnet, which would be the normal mode of operation with IPv4 on p2p links because those links don't have addresses and there is no ARP. With v6 on the other hand, ND can work on all link types and PPP does negotiate an address of sorts.
So whether this actually happens on a true point-to-point link is open with IPv6, and if it's a point-to-point ethernet or similar link you only get some neighbor discovery traffic that goes nowhere, not an increase in actual traffic.
