IPv6 Gap Analysis with Open Daylight Oxygen
===========================================
This section provides users with IPv6 gap analysis regarding feature requirement with
Open Daylight Oxygen 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 Oxygen Official Release.
**Open Daylight Oxygen Status**
In Open Daylight Oxygen 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 Oxygen official release:
* "IPv6 L3VPN Dual Stack with Single router" [3]_
* "IPv6 Inter Data Center using L3VPNs" [4]_

:class: longtable
+--------------------------------------------------+-------------------------+--------------------------------------------------------------+
|Use Case / Requirement |Supported in ODL Oxygen |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: |**NO** |This feature is targeted for Flourine Release. |
| | |In ODL Oxygen Release, RFE "IPv6 Inter-DC L3 North-South |
|3. External routing (north-south) | |Connectivity Using L3VPN Provider Network Types" Spec [1]_ is |
| | |merged. But the code patch has not been merged yet. |
| | |On the other hand, "IPv6 Cluster Support" is available in |
| | |Oxygen Release [2]_. Basically, existing IPv6 features were |
| | |enhanced to work in a three node ODL Clustered Setup. |
+--------------------------------------------------+-------------------------+--------------------------------------------------------------+
|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. |Yes |Targeted for Flourine Release |
+--------------------------------------------------+-------------------------+--------------------------------------------------------------+
|ODL on an IPv6 only Infrastructure. |Yes |Deploying OpenStack with ODL on an IPv6 only infrastructure |
| | |where the API endpoints are all IPv6 addresses. |
+--------------------------------------------------+-------------------------+--------------------------------------------------------------+
|VxLAN Tunnels with IPv6 Endpoints |Yes | |
+--------------------------------------------------+-------------------------+--------------------------------------------------------------+
|IPv6 L3VPN Dual Stack with Single router |Yes |Refer to "Dual Stack VM support in OpenDaylight" Spec [3]_. |
+--------------------------------------------------+-------------------------+--------------------------------------------------------------+
|IPv6 Inter Data Center using L3VPNs |Yes |Refer to "IPv6 Inter-DC L3 North-South connectivity using |
| | |L3VPN provider network types" Spec [4]_. |
