Description

frr_ospf6d.inc:

                                list($interface_ip, $interface_subnet, $subnet) = frr_get_interfaceinfo($conf['interface'], true);
                                if (empty($interface_ip)) {
                                        continue;
                                }
                                $interface_area = (strlen($conf['interfacearea']) > 0) ? $conf['interfacearea'] : $ospf6d_conf['area'];

This makes it impossible to assign IPV6 interfaces to any area if they are configured with "ipv6 address: none". They do have a link-local address which is by all means a valid way to run OSPFv3. You may configure other properties, but you end up with interfaces "not attached to any area". For IPv6 interfaces I think it is safe to skip the IP address check, because there always is one.
