-*****************************************************
-_`Step 1: Disable odl-l3 and Enable neutron-l3-agent`
-*****************************************************
-
-This step is optional, and only needed if you didn't choose to enable neutron-l3-agent during previous installation of
-OPNFV Brahmaputra Release.
-
-If you have chosen to enable neutron-l3-agent during installation, please skip this step and directly go to
-`Step 2: Start Open Daylight`_.
-
-# Place holder for instructions of how to disable odl-l3 and enable neutron-l3-agent
-
-******************************
-_`Step 2: Start Open Daylight`
-******************************
-
-**Note: we assume that you have installed Open Daylight through OPNFV Installer in prior chapters. However, if Open Daylight is not installed, please go to** ``http://www.opendaylight.org/downloads`` **to download and install Open Daylight**
-
-ODL-1: Login to Open Daylight Controller Node. For the purpose of example, we use ``opnfv`` as username of login, and
-``opnfv-odl-controller`` as hostname of the Open Daylight Controller Node.
-
-ODL-2: Start a new terminal session, and change directory to where Open Daylight is installed. Here we use ``odl``
-directory name and ``Lithium SR2`` installation as an example.
-
- ``cd ~/odl/distribution-karaf-0.3.2-Lithium-SR2/bin``
-
-ODL-3: Run the ``karaf`` shell. Please note that it is recommended to run the command in a ``screen`` session.
-
-| ``screen -S ODL_Controller``
-| ``./karaf``
-
-ODL-4: You are now in the Karaf shell of Open Daylight. To explore the list of available features you can execute
-``feature:list``. In order to enable Open Daylight with Open Stack, you have to load the ``odl-ovsdb-openstack``
-feature.
-
- ``opendaylight-user@opnfv>feature:install odl-ovsdb-openstack``
-
-ODL-5: Verify that OVSDB feature is installed successfully.
-
-| ``opendaylight-user@opnfv>feature:list -i | grep ovsdb``
-| odl-ovsdb-openstack | 1.1.1-Lithium-SR1 | x | ovsdb-1.1.1-Lithium-SR1 | OpenDaylight :: OVSDB :: OpenStack Network Virtual
-| odl-ovsdb-southbound-api | 1.1.1-Lithium-SR1 | x | odl-ovsdb-southbound-1.1.1-Lithium-SR1 | OpenDaylight :: southbound :: api
-| odl-ovsdb-southbound-impl | 1.1.1-Lithium-SR1 | x | odl-ovsdb-southbound-1.1.1-Lithium-SR1 | OpenDaylight :: southbound :: impl
-| odl-ovsdb-southbound-impl-rest|1.1.1-Lithium-SR1 | x | odl-ovsdb-southbound-1.1.1-Lithium-SR1| OpenDaylight :: southbound :: impl :: REST
-| odl-ovsdb-southbound-impl-ui | 1.1.1-Lithium-SR1| x | odl-ovsdb-southbound-1.1.1-Lithium-SR1| OpenDaylight :: southbound :: impl :: UI
-| ``opendaylight-user@opnfv>``
-
-ODL-6: To view the logs, you can use the following commands (or alternately the file data/log/karaf.log).
-
-| ``opendaylight-user@opnfv>log:display``
-| ``opendaylight-user@opnfv>log:tail``
-
-ODL-7: To enable ODL DLUX UI, install the following features. Then you can navigate to
-``http://<opnfv-odl-controller IP address>:8181/index.html`` for DLUX UI.
-The default user-name and password is admin/admin.
-
- ``opendaylight-user@opnfv>feature:install odl-restconf odl-l2switch-switch odl-mdsal-apidocs odl-dlux-core``
-
-ODL-8: To exit out of screen session, please use the command ``CTRL+a`` followed by ``d``
-
-**Note: Do not kill the screen session, it will terminate the ODL controller.**
-
-At this moment, Open Daylight has been started successfully.
-
-**********************************************
-_`Step 3: Start Open Stack on Controller Node`
-**********************************************
-
-OS-N-1: Login to Open Stack Controller Node. For the purpose of example, we use ``opnfv`` as username of login, and
-``opnfv-os-controller`` as hostname of the Open Stack Controller Node.
-
-OS-N-2: Start a new terminal, and change directory to where Open Stack is installed. Here we use ``devstack`` directory
-name as an example.
-
- ``cd ~/devstack``
-
-OS-N-3: Create a ``local.conf`` file with the contents from the following URL.
-
- ``http://fpaste.org/276949/39476214/``
-
-Note 1: You need to change the value of ``BRANCH``, and all appearance of ``stable/kilo`` and related URL to point to
-the actual branch of your upstream repository.
-
-Note 2: you need to change the IP address of ``ODL_MGR_IP`` to point to your actual IP address of Open Daylight
-Controller.
-
-Note 3: You may have to change the value of ``ODL_PROVIDER_MAPPINGS`` and ``PUBLIC_INTERFACE`` to match your actual
-network interfaces.
-
-OS-N-4: Initiate Openstack setup by invoking ``stack.sh``
-
- ``./stack.sh``
-
-OS-N-5: If the setup is successful you would see the following logs on the console. Please note that the IP addresses
-are all for the purpose of example. Your IP addresses will match the ones assigned during the installation of OPNFV B
-Release base platform in prior chapters.
-
-| ``This is your host ip: <opnfv-os-controller IP address>``
-| ``Horizon is now available at http://<opnfv-os-controller IP address>/``
-| ``Keystone is serving at <opnfv-os-controller IP address>/``
-| ``The default users are: admin and demo``
-| ``The password: password``
-
-OS-N-6: Assuming that all goes well, you can set ``OFFLINE=True`` and ``RECLONE=no`` in ``local.conf`` to lock the
-codebase. Devstack uses these configuration parameters to determine if it has to run with the existing codebase or
-update to the latest copy.
-
-OS-N-7: Source the credentials.
-
- ``opnfv@opnfv-os-controller:~/devstack$ source openrc admin demo``
-
-OS-N-8: Verify some commands to check if setup is working fine.

+Setup in OpenStack and 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 base platform, the instructions
+are as follows.
+
+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**.
+

+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
+
+**********
+Next Steps
+**********
+
+Congratulations, you have completed the setup of using a service VM to act as an IPv6 vRouter. This setup allows further
+open innovation by any 3rd-party. Please refer to relevant sections in User's Guide for further value-added services on
+this IPv6 vRouter.

+======================================================================
+Set Up a Service VM as an IPv6 vRouter in Native OpenStack Environment
+======================================================================
+
+If you intend to set up a service VM as an IPv6 vRouter in native OpenStack environment of
+OPNFV Brahmaputra Release base platform, the instructions are as follows.
+
+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
+ native OpenStack 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
+
