From rc.conf(5):

            Instead of setting the ifconfig variables as
            ifconfig_<interface> they should be set as
            ipv6_ifconfig_<interface>.  Aliases should be set as
            ipv6_ifconfig_<interface>_alias<n>.

The default router should fall into place once you have an interface that 
is able to contact it - otherwise route will refuse to add.
