Hi,

The problem is still present.

[root at vultr-paris ~]# ping6 fe80::2bd:6ff:fe17:ff00%tap0
ping6: UDP connect: Network is unreachable
[root at vultr-paris ~]# route -6 add fe80::%tap0/64 -iface tap0 -nostatic
add net fe80::%tap0/64: gateway tap0
[root at vultr-paris ~]# ping6 fe80::2bd:6ff:fe17:ff00%tap0

I need to add the route on the target and it's works.

Thanks
