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 Fluorine Official Release. + +**Open Daylight Fluorine Status** + +In Open Daylight Fluorine official release, the legacy ``Old Netvirt`` identified by feature +``odl-ovsdb-openstack`` is deprecated and no longer supported. The ``New Netvirt`` +identified by feature ``odl-netvirt-openstack`` is used. + +Two new features are supported in Open Daylight Fluorine official release: + +* Support for advertising MTU info in IPv6 RAs +* IPv6 external connectivity for FLAT/VLAN based provider networks + +.. table:: + :class: longtable + + +--------------------------------------------------+-------------------------+--------------------------------------------------------------+ + |Use Case / Requirement |Supported in ODL Fluorine|Notes | + +==================================================+=========================+==============================================================+ + |REST API support for IPv6 subnet creation in ODL |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: |Yes | | + | | | | + |1.
