Actually; *on an interface. one way to use v4-w-v6 nh in practice is binding the v4 address to lo (granted, on routers, but this also holds for packets they originate); Similarly, it makes--at least--sense for dual-homed hosts. Then again, even with a v4 /32 bound to an external interface, you would need a host route for, at least, the GW to make this work with ARP. Otherwise, > And if it's a router, then I'd find it more natural to use ARP, with > the undefined address in the ar$spa field. That would require touching implementations to a similar degree, as currently a host is unlikely to respond to an ARP packet from a non- local ar$spa, no? And if that has to be done anyway, going for NDP (i.e.: L3) would make more sense? With best regards, Tobias -- Dr.-Ing.
