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** |**Partial** |IPv6 Router support is work in progress in ODL. |
| | | | |
|1. Communication between VMs on same compute node | | |Currently communication between VMs on the same network is |
|2. Communication between VMs on different compute | | |supported, and the support for the other modes is work in |
| nodes (east-west) | | |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** |**Partial** |Security Groups for IPv6 is a work in progress, and some |
|TCP, UDP) in security groups. Ability to control | | |partial support is available. |
|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. |
