Hi Benoit, I managed to repeat this bug. As a workaround, add an IPv4 address to the outgoing interface (vlan200 in your case), ``` # ifconfig vlan200 inet x.x.x.x/y ``` then retry adding the route ``` # route add -net 10.200.1.1/32 -inet6 fe80::9439:36ff:fef0:7cbd%vlan200 ``` > >> ``` >> >> ping6 to `fe80::9439:36ff:fef0:7cbd%vlan200` works.
