IPv6 Gap Analysis with Open Daylight Carbon
===========================================
This section provides users with IPv6 gap analysis regarding feature requirement with
Open Daylight Carbon 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 Carbon Official Release.
**Open Daylight Carbon Status**
In Open Daylight Carbon 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.

:class: longtable
+--------------------------------------------------+-----------------------+--------------------------------------------------------------+
|Use Case / Requirement |Supported in ODL Carbon|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. Communication between VMs on same network | | |
+--------------------------------------------------+-----------------------+--------------------------------------------------------------+
|IPv6 Router support in ODL: |Yes | |
| | | |
|2. Communication between VMs on different | | |
| networks connected to the same router | | |
| (east-west) | | |
+--------------------------------------------------+-----------------------+--------------------------------------------------------------+
|IPv6 Router support in ODL: |**Work in Progress** |Work in progress. |
| | | |
|3. External routing (north-south) | | |
+--------------------------------------------------+-----------------------+--------------------------------------------------------------+
|IPAM: Support for IPv6 Address assignment modes. |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 | |
|compatible with IPv6. | | |
+--------------------------------------------------+-----------------------+--------------------------------------------------------------+
|Full support for IPv6 matching (i.e. IPv6, ICMPv6,|Yes | |
|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 | |
+--------------------------------------------------+-----------------------+--------------------------------------------------------------+
|IPv6 external L2 VLAN directly attached to a VM. |**ToDo** | |
+--------------------------------------------------+-----------------------+--------------------------------------------------------------+
|ODL on an IPv6 only Infrastructure. |**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 |Yes | |
+--------------------------------------------------+-----------------------+--------------------------------------------------------------+
