Title:
  IPv6 Subnets configured to use external router should not be allowed
  to associate to Neutron Router.

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  IPv6 subnet attributes have various possibilities as described in the following BP.
  http://specs.openstack.org/openstack/neutron-specs/specs/juno/ipv6-radvd-ra.html#rest-api-impact

  Currently Neutron allows attaching a subnet (configured to use an external router, by only setting ipv6_address_mode = slaac and leaving ipv6_ra_mode unset) to Neutron Router.
  Ideally Neutron should not allow this operation and should return an appropriate error message to the user.

  Please refer to the following thread for more details:
