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.
