IPv6 DHCP Routing

This seems to be a normal behaviors, because we dont have possibility to
specify the prefix length in DHCPv6, so every simgle machine will have
/128, then even if they are all on the same link we'll have routing, to
avoid this,
You can ask your router sending RA, to set the "L" flag to tell nodes to
consider that they are on the same link, this way you could avoid all
trafic to pass through the GW. And set manegement flag as well
