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.
.. table::
:class: longtable
+-------------------------------------------------------------+----------------------+--------------------------------------------------------------------------+
|Use Case / Requirement |Supported in ODL Boron|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. However, in Boron release, ODL net-virt provider |
| | |does not support IPv6 features (i.e., the actual functionality is missing |
| | |and would be available only in the later releases of ODL). |
+-------------------------------------------------------------+----------------------+--------------------------------------------------------------------------+
|IPv6 Router support in ODL |**No** |ODL net-virt provider in Boron release only supports IPv4 Router. |
| | | |
|1. Communication between VMs on same compute node | |In the meantime, if IPv6 Routing is necessary, we can use ODL for L2 |
|2. Communication between VMs on different compute nodes | |connectivity and Neutron L3 agent for IPv4/v6 routing. |
| (east-west) | | |
|3. External routing (north-south) | | |
+-------------------------------------------------------------+----------------------+--------------------------------------------------------------------------+
|IPAM: Support for IPv6 Address assignment modes. |**No** |Although it is possible to create different types of IPv6 subnets in ODL, |
| | |ODL_L3 would have to implement the IPv6 Router that can send out Router |
|1. SLAAC | |Advertisements based on the IPv6 addressing mode. Router Advertisement |
|2. DHCPv6 Stateless | |is also necessary for VMs to configure the default route. |
|3. DHCPv6 Stateful | | |
+-------------------------------------------------------------+----------------------+--------------------------------------------------------------------------+
|When using ODL for L2 forwarding/tunneling, it is compatible |Yes | |
|with IPv6. | | |
+-------------------------------------------------------------+----------------------+--------------------------------------------------------------------------+
|Full support for IPv6 matching (i.e., IPv6, ICMPv6, TCP, UDP)|**No** |Security Groups for IPv6 is a work in progress. |
|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. |**ToDo** |Deploying OpenStack with ODL on an IPv6 only infrastructure where the API |
| | |endpoints are all IPv6 addresses. |
