+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``
+
+.. table::

+ |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. |
