Hi<br>
<br>
I think that older kernels (ones that report IPv6 ECMP routes as multiple<br>
routes) do not support weight for IPv6. On Jessie, i cannot set IPv6<br>
weighted ECMP even using 'ip route add'.<br>
<br>
Not sure about newer kernels. BIRD uses older IPv6-ECMP API for route<br>
changes (to be compatible with older kernels), so we do not support<br>
weight here neither.<br>
