Try: ping6 -I eth0 fe80::2e0:c5ff:febc:4aa3

or whatever interface it is on.
Also try:

ping6 -I eth0 ff02::1 (all hosts)
ping6 -I eth0 ff02::2 (all routers)

some ping6 apps also allow "ping6 ff02::1%eth0" or instead of eth0 the
linknumber, though -I always works correctly how you expect it to.

That is because with a link-local address you have to specify the link
(read: interface) ;)
