The following table lists the use cases / feature requirements of VIM-agnostic IPv6 functionality, including infrastructure layer and VNF (VM) layer, and its gap analysis with Open Daylight Carbon Official Release. **Open Daylight Carbon Status** There are 2 options in Open Daylight Carbon to provide Virtualized Networks: 1 ``Old Netvirt``: netvirt implementation used in Open Daylight Beryllium and Boron Release identified by feature ``odl-ovsdb-openstack`` 2 ``New Netvirt``: netvirt implementation which will replace the Old Netvirt in the future releases based on a more modular design. It is identified by feature ``odl-netvirt-openstack`` Please **NOTE** that in terms of IPv6 support in OpenDaylight, there is no difference between **Carbon** release and **Boron** release. .. table:: :class: longtable +--------------------------------------------------+-----------------------------------------------+--------------------------------------------------------------+ |Use Case / Requirement | Supported in ODL Carbon |Notes | | +----------------------+------------------------+ | | | Old Netvirt | New Netvirt | | | |(odl-ovsdb-openstack) |(odl-netvirt-openstack) | | +==================================================+======================+========================+==============================================================+ |REST API support for IPv6 subnet creation in ODL |Yes |Yes |Yes, it is possible to create IPv6 subnets in ODL using | | | | |Neutron REST API. | | | | | | | | | |For a network which has both IPv4 and IPv6 subnets, ODL | | | | |mechanism driver will send the port information which | | | | |includes IPv4/v6 addresses to ODL Neutron northbound API. | | | | |When port information is queried, it displays IPv4 and IPv6 | | | | |addresses. | +--------------------------------------------------+----------------------+------------------------+--------------------------------------------------------------+ |IPv6 Router support in ODL: |**No** |Yes | | | | | | | |1.
