+IPv6 Configuration - Setting Up a Service VM as an IPv6 vRouter
+===============================================================
+
+This section provides instructions to set up a service VM as an IPv6 vRouter using OPNFV Brahmaputra Release
+installers. The environment may be pure OpenStack option or Open Daylight L2-only option.
+The deployment model may be HA or non-HA. The infrastructure may be bare metal or virtual environment.
+
+For complete instructions and documentations of setting up service VM as an IPv6 vRouter using ANY method,
+please refer to:
+
+1. IPv6 Configuration Guide (HTML): http://artifacts.opnfv.org/ipv6/docs/setupservicevm/index.html
+2. IPv6 User Guide (HTML): http://artifacts.opnfv.org/ipv6/docs/gapanalysis/index.html
+
+****************************
+Pre-configuration Activities
+****************************
+
+The configuration will work in 2 environments:
+
+1. OpenStack-only environment
+2. OpenStack with Open Daylight L2-only environment
+
+Depending on which installer will be used to deploy OPNFV, each environment may be deployed
+on bare metal or virtualized infrastructure. Each deployment may be HA or non-HA.
+
+Refer to the previous installer configuration chapters, installations guide and release notes.
+
+******************************************
+Setup Manual in OpenStack-Only Environment
+******************************************
+
+If you intend to set up a service VM as an IPv6 vRouter in OpenStack-only environment of
+OPNFV Brahmaputra Release, please **NOTE** that:
+
+* Because the anti-spoofing rules of Security Group feature in OpenStack prevents
+  a VM from forwarding packets, we need to disable Security Group feature in the
+  OpenStack-only environment.
+* The hostnames, IP addresses, and username are for exemplary purpose in instructions.
+  Please change as needed to fit your environment.
+* The instructions apply to both deployment model of single controller node and
+  HA (High Availability) deployment model where multiple controller nodes are used.
+

+
+**OPNFV-NATIVE-SETUP-16**: Boot Service VM (``vRouter``), VM1 and VM2
+
+.. code-block:: bash
+
+    nova boot --image Fedora22 --flavor m1.small --user-data /opt/stack/opnfv_os_ipv6_poc/metadata.txt --availability-zone nova:opnfv-os-compute --nic port-id=$(neutron port-list | grep -w eth0-vRouter | awk '{print $2}') --nic port-id=$(neutron port-list | grep -w eth1-vRouter | awk '{print $2}') --key-name vRouterKey vRouter
+    nova list
+    nova console-log vRouter #Please wait for some 10 to 15 minutes so that necessary packages (like radvd) are installed and vRouter is up.
+    nova boot --image cirros-0.3.4-x86_64-uec --flavor m1.tiny --nic port-id=$(neutron port-list | grep -w eth0-VM1 | awk '{print $2}') --availability-zone nova:opnfv-os-controller --key-name vRouterKey --user-data /opt/stack/opnfv_os_ipv6_poc/set_mtu.sh VM1
+    nova boot --image cirros-0.3.4-x86_64-uec --flavor m1.tiny --nic port-id=$(neutron port-list | grep -w eth0-VM2 | awk '{print $2}') --availability-zone nova:opnfv-os-compute --key-name vRouterKey --user-data /opt/stack/opnfv_os_ipv6_poc/set_mtu.sh VM2
+    nova list # Verify that all the VMs are in ACTIVE state.
+
+**OPNFV-NATIVE-SETUP-17**: If all goes well, the IPv6 addresses assigned to the VMs
+would be as shown as follows:
+
+.. code-block:: bash
+
+    vRouter eth0 interface would have the following IPv6 address: 2001:db8:0:1:f816:3eff:fe11:1111/64
+    vRouter eth1 interface would have the following IPv6 address: 2001:db8:0:2::1/64
+    VM1 would have the following IPv6 address: 2001:db8:0:2:f816:3eff:fe33:3333/64
+    VM2 would have the following IPv6 address: 2001:db8:0:2:f816:3eff:fe44:4444/64
+
+**OPNFV-NATIVE-SETUP-18**: Now we can ``SSH`` to ``vRouter``.
+
+Please **NOTE** that in case of HA (High Availability) deployment model where multiple controller
+nodes are used, ``ipv6-router`` created in step **OPNFV-NATIVE-SETUP-4** could be in any of the controller
+node. Thus you need to identify in which controller node ``ipv6-router`` is created in order to
+enter the ``ipv6-router`` namespace. The following command in Neutron will display the
+controller on which the ``ipv6-router`` is spawned.
+
+.. code-block:: bash
+
+    neutron l3-agent-list-hosting-router ipv6-router
+
+Then you login to that controller.
+
+To ``SSH`` to ``vRouter``, you can execute the following command.
+
+.. code-block:: bash
+
+    sudo ip netns exec qrouter-$(neutron router-list | grep -w ipv6-router | awk '{print $2}') ssh -i ~/vRouterKey fedora@2001:db8:0:1:f816:3eff:fe11:1111

+****************************************************************
+Setup Manual in OpenStack with Open Daylight L2-Only Environment
+****************************************************************
+
+If you intend to set up a service VM as an IPv6 vRouter in an environment of OpenStack
+and Open Daylight L2-only of OPNFV Brahmaputra Release, please **NOTE** that:
+
+* The hostnames, IP addresses, and username are for exemplary purpose in instructions.
+  Please change as needed to fit your environment.
+* The instructions apply to both deployment model of single controller node and
+  HA (High Availability) deployment model where multiple controller nodes are used.
+* However, in case of HA, when ``ipv6-router`` is created in step **SETUP-SVM-11**,
+  it could be created in any of the controller node. Thus you need to identify in which
+  controller node ``ipv6-router`` is created in order to manually spawn ``radvd`` daemon
+  inside the ``ipv6-router`` namespace in steps **SETUP-SVM-24** through **SETUP-SVM-30**.

+and ``eth1`` interface on ``ipv4-int-network1`` connecting to ``ipv4-router``.
+
+**SETUP-SVM-19**: Boot the ``vRouter`` using ``Fedora22`` image on the OpenStack Compute Node with hostname
+``opnfv-os-compute``
+

+
+Please **note** that ``/opt/stack/opnfv_os_ipv6_poc/metadata.txt`` is used to enable the ``vRouter`` to automatically
+spawn a ``radvd``, and
+
+* Act as an IPv6 vRouter which advertises the RA (Router Advertisements) with prefix

+Boot Two Other VMs in ``ipv4-int-network1``
+-------------------------------------------
+
+In order to verify that the setup is working, let us create two cirros VMs with ``eth1`` interface on the
+``ipv4-int-network1``, i.e., connecting to ``vRouter`` ``eth1`` interface for internal network.
+
+We will have to configure appropriate ``mtu`` on the VMs' interface by taking into account the tunneling
+overhead and any physical switch requirements. If so, push the ``mtu`` to the VM either using ``dhcp``
+options or via ``meta-data``.
+
+**SETUP-SVM-21**: Create VM1 on OpenStack Controller Node with hostname ``opnfv-os-controller``
+
+.. code-block:: bash
+
+    nova boot --image cirros-0.3.4-x86_64-uec --flavor m1.tiny --nic port-id=$(neutron port-list | grep -w eth0-VM1 | awk '{print $2}') --availability-zone nova:opnfv-os-controller --key-name vRouterKey --user-data /opt/stack/opnfv_os_ipv6_poc/set_mtu.sh VM1
+
+**SETUP-SVM-22**: Create VM2 on OpenStack Compute Node with hostname ``opnfv-os-compute``
+
+.. code-block:: bash
+
+    nova boot --image cirros-0.3.4-x86_64-uec --flavor m1.tiny --nic port-id=$(neutron port-list | grep -w eth0-VM2 | awk '{print $2}') --availability-zone nova:opnfv-os-compute --key-name vRouterKey --user-data /opt/stack/opnfv_os_ipv6_poc/set_mtu.sh VM2
+
+**SETUP-SVM-23**: Confirm that both the VMs are successfully booted.
+
+.. code-block:: bash
+
+    nova list
+    nova console-log VM1
+    nova console-log VM2
+
+----------------------------------
+Spawn ``RADVD`` in ``ipv6-router``
+----------------------------------
+
+Let us manually spawn a ``radvd`` daemon inside ``ipv6-router`` namespace to simulate an external router.
+First of all, we will have to identify the ``ipv6-router`` namespace and move to the namespace.
+
+Please **NOTE** that in case of HA (High Availability) deployment model where multiple controller
+nodes are used, ``ipv6-router`` created in step **SETUP-SVM-11** could be in any of the controller
+node. Thus you need to identify in which controller node ``ipv6-router`` is created in order to manually
+spawn ``radvd`` daemon inside the ``ipv6-router`` namespace in steps **SETUP-SVM-24** through
+**SETUP-SVM-30**. The following command in Neutron will display the controller on which the
+``ipv6-router`` is spawned.
+
+.. code-block:: bash
+
+    neutron l3-agent-list-hosting-router ipv6-router
+
+Then you login to that controller and execute steps **SETUP-SVM-24**
+through **SETUP-SVM-30**
+
+**SETUP-SVM-24**: identify the ``ipv6-router`` namespace and move to the namespace
+
+.. code-block:: bash
+
+    sudo ip netns exec qrouter-$(neutron router-list | grep -w ipv6-router | awk '{print $2}') bash
+
+**SETUP-SVM-25**: Upon successful execution of the above command, you will be in the router namespace.
+Now let us configure the IPv6 address on the <qr-xxx> interface.
+
+.. code-block:: bash
+
+    export router_interface=$(ip a s | grep -w "global qr-*" | awk '{print $7}')
+    ip -6 addr add 2001:db8:0:1::1 dev $router_interface
+
+**SETUP-SVM-26**: Update the sample file ``/opt/stack/opnfv_os_ipv6_poc/scenario2/radvd.conf``
+with ``$router_interface``.
+
+.. code-block:: bash
+
+    cp /opt/stack/opnfv_os_ipv6_poc/scenario2/radvd.conf /tmp/radvd.$router_interface.conf
+    sed -i 's/$router_interface/'$router_interface'/g' /tmp/radvd.$router_interface.conf
+
+**SETUP-SVM-27**: Spawn a ``radvd`` daemon to simulate an external router. This ``radvd`` daemon advertises an IPv6
+subnet prefix of ``2001:db8:0:1::/64`` using RA (Router Advertisement) on its $router_interface so that ``eth0``
+interface of ``vRouter`` automatically configures an IPv6 SLAAC address.
+
+.. code-block:: bash
+
+    $radvd -C /tmp/radvd.$router_interface.conf -p /tmp/br-ex.pid.radvd -m syslog
+
+**SETUP-SVM-28**: Add an IPv6 downstream route pointing to the ``eth0`` interface of vRouter.
+
+.. code-block:: bash
+
+    ip -6 route add 2001:db8:0:2::/64 via 2001:db8:0:1:f816:3eff:fe11:1111
+
+**SETUP-SVM-29**: The routing table should now look similar to something shown below.
+
+.. code-block:: bash
+
+    ip -6 route show
+    2001:db8:0:1::1 dev qr-42968b9e-62 proto kernel metric 256
+    2001:db8:0:1::/64 dev qr-42968b9e-62 proto kernel metric 256 expires 86384sec
+    2001:db8:0:2::/64 via 2001:db8:0:1:f816:3eff:fe11:1111 dev qr-42968b9e-62 proto ra metric 1024 expires 29sec
+    fe80::/64 dev qg-3736e0c7-7c proto kernel metric 256
+    fe80::/64 dev qr-42968b9e-62 proto kernel metric 256
+
+**SETUP-SVM-30**: If all goes well, the IPv6 addresses assigned to the VMs would be as shown as follows:
+
+.. code-block:: bash
+
+    vRouter eth0 interface would have the following IPv6 address: 2001:db8:0:1:f816:3eff:fe11:1111/64
+    vRouter eth1 interface would have the following IPv6 address: 2001:db8:0:2::1/64
+    VM1 would have the following IPv6 address: 2001:db8:0:2:f816:3eff:fe33:3333/64
+    VM2 would have the following IPv6 address: 2001:db8:0:2:f816:3eff:fe44:4444/64
+
+--------------------------------
+Testing to Verify Setup Complete
+--------------------------------
+
+Now, let us ``ssh`` to one of the VMs, e.g. VM1, to confirm that it has successfully configured the IPv6 address
+using ``SLAAC`` with prefix ``2001:db8:0:2::/64`` from ``vRouter``.
+
+Please note that you need to get the IPv4 address associated to VM1. This can be inferred from ``nova list`` command.
+
+**SETUP-SVM-31**: ``ssh`` VM1
+
+.. code-block:: bash
+
+    ssh -i /home/odl/vRouterKey cirros@<VM1-IPv4-address>
+
+If everything goes well, ``ssh`` will be successful and you will be logged into VM1. Run some commands to verify
+that IPv6 addresses are configured on ``eth0`` interface.
+
+**SETUP-SVM-32**: Show an IPv6 address with a prefix of ``2001:db8:0:2::/64``
+
+.. code-block:: bash
+
+    ip address show
+
+**SETUP-SVM-33**: ping some external IPv6 address, e.g. ``ipv6-router``
+
+.. code-block:: bash
+
+    ping6 2001:db8:0:1::1
+
+If the above ping6 command succeeds, it implies that ``vRouter`` was able to successfully forward the IPv6 traffic
+to reach external ``ipv6-router``.
+
+**SETUP-SVM-34**: When all tests show that the setup works as expected, You can now exit the ``ipv6-router`` namespace.
+
+.. code-block:: bash
+
+    exit
+

+Congratulations, you have completed the setup of using a service VM to act as an IPv6 vRouter.
+You have validated the setup based on the instruction in previous sections. If you want to further
+test your setup, you can ``ping6`` among ``VM1``, ``VM2``, ``vRouter`` and ``ipv6-router``.
+
+This setup allows further open innovation by any 3rd-party. For more instructions and documentations,
+please refer to:
 
-note: this section should be singular and derived from the test projects
-once we have one test suite to run for all deploy tools.  This is not the
-case yet so each deploy tool will need to provide (hopefully very simillar)
-documentation of this.
