Perhaps playing around with link-local multicast addresses?
What about:
# ping6 -I eth0 ff02::1
PING ff02::1(ff02::1) from fe80::0123:45ff:fe67:890a eth0: 56 data
bytes
64 bytes from ::1: icmp_seq=1 ttl=64 time=0.107 ms
64 bytes from fe80::5678:9aff:febc:def0: icmp_seq=1 ttl=64 time=0.525
ms (DUP!)
Oh, perhaps a new switch in kernel is necessary whether reply on a
multicast IPv6 ping...for security issues, similar to IPv4's
net.ipv4.icmp_echo_ignore_broadcasts (linux)
