Doesn't seem to work :-?
You need to specify which network, ie. which interface -
ping -c2 ff02::1%eth0
Which I tried before and failed. First paragraph above.
I see no such attempt in what you posted. What I do see is "ping -c 2 FE80::1%eth0" .....
Need new set of eyes.
Here ia snippet from my system:
