Yes, the link-local address can't be used like that - TBH, I don't know why. For ping6, you need to specify the interface:
ping6 -I ethX FE80::21E:BFF:FE08:4CCB
Ah, yes, I remember that now. As I don't use v6 and I can't understand the reason of having to specify the interface, so I always forget that detail.
I've discovered the reason - the link local address may be assigned to multiple interfaces, so to use it, you need to specify which interface. -- Per Jessen, Zürich (3.0°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Actually, the computer cannot know which interface a link local address is on, unless it's somehow told. In the case of routers, the router will announce itself and the computer will know which interface it's connected to. So, if you're manually doing something, such as ping, you have to specify the interface. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Is that what happens during auto configuration or is there another way of telling it? 'ip addr' appears to show e.g. eth0 having a link-local address. -- Per Jessen, Zürich (5.5°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It may know where your NIC is, but not the next computers. As I mentioned, routers advertise themselves to other devices. I don't think individual computer do. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
