+Install OPNFV on IPv6-Only Infrastructure
+=========================================
+
+This section provides instructions to install OPNFV on IPv6-only Infrastructure. All underlay networks
+and API endpoints will be IPv6-only except:
+
+1. "admin" network in underlay/undercloud still has to be IPv4, due to lack of support of IPMI
+   over IPv6 or PXE over IPv6.
+2. OVS VxLAN (or GRE) tunnel endpoint is still IPv4 only, although IPv6 traffic can be
+   encapsulated within the tunnel.
+3. Metadata server is still IPv4 only.
+
+Except the limitations above, the use case scenario of the IPv6-only infrastructure includes:
+
+1. Support OPNFV deployment on an IPv6 only infrastructure.
+2. Horizon/ODL-DLUX access using IPv6 address from an external host.
+3. OpenStack API access using IPv6 addresses from various python-clients.
+4. Ability to create Neutron Routers, IPv6 subnets (e.g. SLAAC/DHCPv6-Stateful/
+   DHCPv6-Stateless) to support North-South traffic.
+5. Inter VM communication (East-West routing) when VMs are spread
+   across two compute nodes.
+6. VNC access into a VM using IPv6 addresses.

+Install OPNFV in OpenStack-Only Environment
+-------------------------------------------
+
+**Apex Installer**:
+
+.. code-block:: bash
+
+    # HA, Virtual deployment in OpenStack-only environment
+    ./opnfv-deploy -v -d /etc/opnfv-apex/os-nosdn-nofeature-ha.yaml \
+    -n /etc/opnfv-apex/network_setting_v6.yaml
+
+    # HA, Bare Metal deployment in OpenStack-only environment
+    ./opnfv-deploy -d /etc/opnfv-apex/os-nosdn-nofeature-ha.yaml \
+    -i <inventory file> -n /etc/opnfv-apex/network_setting_v6.yaml
+
+    # Non-HA, Virtual deployment in OpenStack-only environment
+    ./opnfv-deploy -v -d /etc/opnfv-apex/os-nosdn-nofeature-noha.yaml \
+    -n /etc/opnfv-apex/network_setting_v6.yaml
+
+    # Non-HA, Bare Metal deployment in OpenStack-only environment
+    ./opnfv-deploy -d /etc/opnfv-apex/os-nosdn-nofeature-noha.yaml \
+    -i <inventory file> -n /etc/opnfv-apex/network_setting_v6.yaml
+
+    # Note:
+    #
+    # 1. Parameter ""-v" is mandatory for Virtual deployment
+    # 2. Parameter "-i <inventory file>" is mandatory for Bare Metal deployment
+    # 2.1 Refer to https://git.opnfv.org/cgit/apex/tree/config/inventory for examples of inventory file
+    # 3. You can use "-n /etc/opnfv-apex/network_setting.yaml" for deployment in IPv4 infrastructure
+
+Please **NOTE** that:
+
+* You need to refer to **installer's documentation** for other necessary
+  parameters applicable to your deployment.
+* You need to refer to **Release Notes** and **installer's documentation** if there is
+  any issue in installation.

+Install OPNFV in OpenStack with ODL-L2 Environment
+--------------------------------------------------
+
+**Apex Installer**:
+
+.. code-block:: bash
+
+    # HA, Virtual deployment in OpenStack with Open Daylight L2-only environment
+    ./opnfv-deploy -v -d /etc/opnfv-apex/os-odl_l2-nofeature-ha.yaml \
+    -n /etc/opnfv-apex/network_setting_v6.yaml
+
+    # HA, Bare Metal deployment in OpenStack with Open Daylight L2-only environment
+    ./opnfv-deploy -d /etc/opnfv-apex/os-odl_l2-nofeature-ha.yaml \
+    -i <inventory file> -n /etc/opnfv-apex/network_setting_v6.yaml
+
+    # Non-HA deployment in OpenStack with Open Daylight L2-only environment
+    # There is no settings file provided by default for odl_l2 non-HA deployment
+    # You need to copy /etc/opnfv-apex/os-odl_l2-nofeature-ha.yaml to another file
+    # e.g. /etc/opnfv-apex/os-odl_l2-nofeature-noha.yaml
+    # and change the "ha_enabled" parameter to be "false", i.e.: "ha_enabled: false", and:
+
+    # - For Non-HA, Virtual deployment
+    ./opnfv-deploy -v -d /etc/opnfv-apex/os-odl_l2-nofeature-noha.yaml \
+    -n /etc/opnfv-apex/network_setting_v6.yaml
+
+    # - For Non-HA, Bare Metal deployment
+    ./opnfv-deploy -d /etc/opnfv-apex/os-odl_l2-nofeature-noha.yaml \
+    -i <inventory file> -n /etc/opnfv-apex/network_setting_v6.yaml
+
+    # Note:
+    #
+    # 1. Parameter ""-v" is mandatory for Virtual deployment
+    # 2. Parameter "-i <inventory file>" is mandatory for Bare Metal deployment
+    # 2.1 Refer to https://git.opnfv.org/cgit/apex/tree/config/inventory for examples of inventory file
+    # 3. You can use "-n /etc/opnfv-apex/network_setting.yaml" for deployment in IPv4 infrastructure
+
+Please **NOTE** that:
+
+* You need to refer to **installer's documentation** for other necessary
+  parameters applicable to your deployment.
+* You need to refer to **Release Notes** and **installer's documentation** if there is
+  any issue in installation.

+-------------------
+Testing Methodology
+-------------------
+
+There are 2 levels of testing to validate the deployment.
+
+++++++++++++++++
+Underlay Testing
+++++++++++++++++
+
+**Underlay** Testing is to validate that API endpoints are listening on IPv6 addresses.
+This can be as simple as validating Keystone service, and as complete as validating each
+API endpoint. It is important to reuse Tempest API testing.
+
+Please **Note** that, to the best of our knowledge, Tempest API testing does not validate
+API endpoints listening on IPv6 addresses. Thus Underlay Testing is postponed to future
+release until Tempest API testing is ready to validate API endpoints listening on IPv6 addresses.
+
++++++++++++++++
+Overlay Testing
++++++++++++++++
+
+**Overlay** Testing is to validate that IPv6 is supported in tenant networks, subnets and routers.
+Both Tempest API testing and Tempest Scenario testing are used in our Overlay Testing.
+
+Tempest API testing validates that the Neutron API supports the creation of IPv6 networks, subnets, routers, etc:
+

+    tempest.api.network.test_ports.PortsIpV6TestJSON.test_list_ports

+    tempest.api.network.test_routers.RoutersIpV6Test.test_add_remove_router_interface_with_port_id

+    tempest.api.network.test_routers.RoutersIpV6Test.test_create_show_list_update_delete_router
+    tempest.api.network.test_security_groups.SecGroupIPv6Test.test_create_list_update_show_delete_security_group
+    tempest.api.network.test_security_groups.SecGroupIPv6Test.test_create_show_delete_security_group_rule
+    tempest.api.network.test_security_groups.SecGroupIPv6Test.test_list_security_groups
+
+Tempest Scenario testing validates some specific overlay IPv6 scenarios
+(i.e. use cases) as follows:
+
+.. code-block:: bash
+
+    tempest.scenario.test_network_v6.TestGettingAddress.test_dhcp6_stateless_from_os
+    tempest.scenario.test_network_v6.TestGettingAddress.test_dualnet_dhcp6_stateless_from_os
+    tempest.scenario.test_network_v6.TestGettingAddress.test_dualnet_multi_prefix_dhcpv6_stateless
+    tempest.scenario.test_network_v6.TestGettingAddress.test_dualnet_multi_prefix_slaac
+    tempest.scenario.test_network_v6.TestGettingAddress.test_dualnet_slaac_from_os
+    tempest.scenario.test_network_v6.TestGettingAddress.test_multi_prefix_dhcpv6_stateless
+    tempest.scenario.test_network_v6.TestGettingAddress.test_multi_prefix_slaac
+    tempest.scenario.test_network_v6.TestGettingAddress.test_slaac_from_os
+
+The above Tempest API testing and Scenario testing are quite comprehensive to validate
+overlay IPv6 tenant networks. They are part of OpenStack default Smoke Tests,
+run in FuncTest and integrated into OPNFV's CI/CD environment.
