Link local addresses are generated at random, just as ipv4 autoip addresses,
only to have some id that does not collide with any in the network. And their
prefix does not indicate anything to the kernel routing table, hence you need to
specify the out interface.

You need some ipv6 dhcp server, or set some easy addresses in both sides. Note
that ipv6 interfaces are meant to have *more* than one ip, so it's only about
*adding* a fixed address, a *dhcp* address, whatever.
