IPv6 Gap Analysis with Open Daylight Boron
==========================================
This section provides users with IPv6 gap analysis regarding feature requirement with
Open Daylight Boron Official Release. 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 Boron Official Release.
**Open Daylight Boron Status**
There are 2 options in Open Daylight Boron to provide Virtualized Networks:
1 ``Old Netvirt``: netvirt implementation used in Open Daylight Beryllium 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``

|Use Case / Requirement | Supported in ODL Boron |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. Communication between VMs on same network | | | |
+--------------------------------------------------+----------------------+------------------------+--------------------------------------------------------------+
|IPv6 Router support in ODL: |**No** |Yes | |
| | | | |
|2. Communication between VMs on different | | | |
| networks connected to the same router | | | |
| (east-west) | | | |
+--------------------------------------------------+----------------------+------------------------+--------------------------------------------------------------+
|IPv6 Router support in ODL: |**No** |**Work in Progress** |Work in progress. |
| | | | |
|3. External routing (north-south) | | | |
+--------------------------------------------------+----------------------+------------------------+--------------------------------------------------------------+
|IPAM: Support for IPv6 Address assignment modes. |**No** |Yes |ODL IPv6 Router supports all the IPv6 Address assignment |
| | | |modes along with Neutron DHCP Agent. |
|1. SLAAC | | | |
|2. DHCPv6 Stateless | | | |
|3. DHCPv6 Stateful | | | |
+--------------------------------------------------+----------------------+------------------------+--------------------------------------------------------------+
|When using ODL for L2 forwarding/tunneling, it is |Yes |Yes | |
|compatible with IPv6. | | | |
+--------------------------------------------------+----------------------+------------------------+--------------------------------------------------------------+
|Full support for IPv6 matching (i.e. IPv6, ICMPv6,|**Partial** |Yes |Security Groups for IPv6 is supported in the new NetVirt. |
|TCP, UDP) in security groups. Ability to control | | | |
|and manage all IPv6 security group capabilities | | | |
|via Neutron/Nova API (REST and CLI) as well as | | | |
|via Horizon | | | |
+--------------------------------------------------+----------------------+------------------------+--------------------------------------------------------------+
|Shared Networks support |Yes |Yes | |
+--------------------------------------------------+----------------------+------------------------+--------------------------------------------------------------+
|IPv6 external L2 VLAN directly attached to a VM. |**ToDo** |**ToDo** | |
+--------------------------------------------------+----------------------+------------------------+--------------------------------------------------------------+
|ODL on an IPv6 only Infrastructure. |**No** |**Work in Progress** |Deploying OpenStack with ODL on an IPv6 only infrastructure |
| | | |where the API endpoints are all IPv6 addresses. |
+--------------------------------------------------+----------------------+------------------------+--------------------------------------------------------------+
|VxLAN Tunnels with IPv6 Endpoints |**No** |**Work in Progress** |The necessary patches are under review to support this use |
| | | |case for OVS 2.6 or higher version. |
