Please attach all the IPv6 subnets including trunk port subnets and subport subnets to the neutron router. Since automatic IPv6 assignment is dependent on router advertisement (RA) packet which is sending from ODL controller on behalf of neutron router.

This configuration is valid for IPv6 subnets RA mode is SLAAC, DHCPv6 stateless and DHCPv6 statefull also.
