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 traffic) when one of the VM is on Controller node
and the other on the Compute node.
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
**Joid** Installer:
.. code-block:: bash
# HA deployment in OpenStack-only environment
./deploy.sh -o mitaka -s nosdn -t ha -l default -f ipv6
# Non-HA deployment in OpenStack-only environment
./deploy.sh -o mitaka -s nosdn -t nonha -l default -f ipv6
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
**Joid** Installer:
.. code-block:: bash
# HA deployment in OpenStack with Open Daylight L2-only environment
./deploy.sh -o mitaka -s odl -t ha -l default -f ipv6
# Non-HA deployment in OpenStack with Open Daylight L2-only environment
./deploy.sh -o mitaka -s odl -t nonha -l default -f ipv6
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.
Tempest Scenario testing covers the following overlay IPv6 scenarios:
.. code-block:: bash
tempest.api.network.test_networks.BulkNetworkOpsIpV6Test.test_bulk_create_delete_network
tempest.api.network.test_networks.BulkNetworkOpsIpV6Test.test_bulk_create_delete_port

tempest.api.network.test_ports.PortsIpV6TestJSON.test_list_ports
tempest.api.network.test_ports.PortsIpV6TestJSON.test_show_port
tempest.api.network.test_routers.RoutersIpV6Test.test_add_multiple_router_interfaces
tempest.api.network.test_routers.RoutersIpV6Test.test_add_remove_router_interface_with_port_id
tempest.api.network.test_routers.RoutersIpV6Test.test_add_remove_router_interface_with_subnet_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
The above scenarios are quite comprehensive to validate IPv6 tenant networks. We are using above
Tempest Scenario testing as Smoke Test in FuncTest, which is integrated into OPNFV's CI/CD environment.
