-The BGPVPN feature enables creation of BGP VPNs according to the OpenStack
+A high-level description of the scenarios is provided in this section.

+
+The BGPVPN feature enables creation of BGP VPNs on the Neutron API according to the OpenStack
 BGPVPN blueprint at https://blueprints.launchpad.net/neutron/+spec/neutron-bgp-vpn.
 In a nutshell, the blueprint defines a BGPVPN object and a number of ways
-how to associate it with the existing Neutron object model, including a unique

 definition of the related semantics. The BGPVPN framework supports a backend
 driver model with currently available drivers for Bagpipe, OpenContrail, Nuage
-and OpenDaylight.
+and OpenDaylight. The OPNFV scenario makes use of the OpenDaylight driver and backend
+implementation through the ODL VPNService project.
+
+Hardware requirements
+=====================
+
+The SDNVPN scenarios can be deployed as a bare-metal or a virtual environment on a single host.
+
+Bare metal deployment on Pharos Lab
+-----------------------------------
+
+Hardware requirements for bare-metal deployments of the OPNFV infrastructure are specified
+by the Pharos project. The Pharos project provides an OPNFV hardware specification for
+configuring your hardware at: http://artifacts.opnfv.org/pharos/docs/pharos-spec.html.
+
+Virtual deployment hardware requirements
+----------------------------------------
+
+To perform a virtual deployment of an OPNFV scenario on a single host, that host has to
+meet the hardware requirements outlined in the <missing spec>.
+
+When ODL is used as an SDN Controller in an OPNFV virtual deployment, ODL is
+running on the OpenStack Controller VMs. It is therefore recommended to
+increase the amount of resources for these VMs.
+
+Our recommendation is to have 2 additional virtual cores and 8GB additional virtual memory
+on top of the normally recommended configuration.
+
+Together with the commonly used recommendation this sums up to:
+::
+
+ 4 virtual cores
+ 16 GB virtual memory
+
+See in Installation section below how to configure this.
+
+Preparing the host to install Fuel by script
+============================================
+.. Not all of these options are relevant for all scenario's.  I advise following the
+.. instructions applicable to the deploy tool used in the scenario.
+
+Before starting the installation of the <scenario> scenario some preparation of the
+machine that will host the Fuel VM must be done.
+
+Installation of required packages
+---------------------------------
+To be able to run the installation of the basic OPNFV fuel installation the
+Jumphost (or the host which serves the VMs for the virtual deployment) needs to
+install the following packages:
+::
+
+ sudo apt-get install -y git make curl libvirt-bin libpq-dev qemu-kvm \
+                         qemu-system tightvncserver virt-manager sshpass \
+                         fuseiso genisoimage blackbox xterm python-pip \
+                         python-git python-dev python-oslo.config \
+                         python-pip python-dev libffi-dev libxml2-dev \
+                        libxslt1-dev libffi-dev libxml2-dev libxslt1-dev \
+                        expect curl python-netaddr p7zip-full
+
+ sudo pip install GitPython pyyaml netaddr paramiko lxml scp \
+                  python-novaclient python-neutronclient python-glanceclient \
+                  python-keystoneclient debtcollector netifaces enum
+
+Download the source code and artifact
+-------------------------------------
+To be able to install the scenario os-odl_l2-bgpvpn one can follow the way
+CI is deploying the scenario.
+First of all the opnfv-fuel repository needs to be cloned:
+::
+
+ git clone ssh://<user>@gerrit.opnfv.org:29418/fuel
+
+This command downloads the whole repository fuel. We need now to switch it to
+the stable Colorado branch:
+::
+
+ cd fuel
+ git checkout stable/colorado
+
+Now download the appropriate OPNFV Fuel ISO into an appropriate folder:
+::
+
+ wget http://artifacts.opnfv.org/fuel/colorado/opnfv-colorado.1.0.iso
+
+The exact name of the ISO image may change.
+Check https://www.opnfv.org/opnfv-colorado-fuel-users to get the latest ISO.
+
+Simplified scenario deployment procedure using Fuel
+===================================================
+
+This section describes the installation of the os-odl_l2-bgpvpn-ha or
+os-odl_l2-bgpvpn-noha OPNFV reference platform stack across a server cluster
+or a single host as a virtual deployment.
+
+Scenario Preparation
+--------------------
+dea.yaml and dha.yaml need to be copied and changed according to the lab-name/host
+where you deploy.
+Copy the full lab config from:
+::
+
+ cp <path-to-opnfv-fuel-repo>/deploy/config/labs/devel-pipeline/elx \
+    <path-to-opnfv-fuel-repo>/deploy/config/labs/devel-pipeline/<your-lab-name>
+
+Add at the bottom of dha.yaml
+::
+
+ disks:
+   fuel: 100G
+   controller: 100G
+   compute: 100G
+
+ define_vms:
+   controller:
+     vcpu:
+       value: 4
+     memory:
+       attribute_equlas:
+         unit: KiB
+       value: 16388608
+     currentMemory:
+       attribute_equlas:
+         unit: KiB
+       value: 16388608
+
+
+Check if the default settings in dea.yaml are in line with your intentions
+and make changes as required.
+
+Installation procedures
+-----------------------
+
+We describe several alternative procedures in the following.
+
+Go to
+::
+
+ cd <opnfv-fuel-repo>/ci
+
+Full automatic virtual deployment High Availablity Mode
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following command will deploy the high-availability flavor of SDNVPN scenario os-odl_l2-bgpvpn-ha
+in a fully automatic way, i.e. all installation steps (Fuel server installation, configuration,
+node discovery and platform deployment) will take place without any further prompt for user input.
+::
+
+ sudo bash ./deploy.sh -b file://<path-to-opnfv-fuel-repo>/config/ -l devel-pipeline -p <your-lab-name> -s os-odl_l2-bgpvpn-ha -i file://<path-to-fuel-iso>
+
+Full automatic virtual deployment NO High Availability Mode
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following command will deploy the SDNVPN scenario in its non-high-availability flavor. Otherwise it does the same as described above.
+::
+
+ sudo bash ./deploy.sh -b file://<path-to-opnfv-fuel-repo>/config/ -l devel-pipeline -p <your-lab-name> -s os-odl_l2-bgpvpn-noha -i file://<path-to-fuel-iso>
+
+Automatic Fuel installation and manual scenario deployment
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+A useful alternative to the full automatic procedure is to only autodeploy the Fuel host and to run host selection, role assignment and SDNVPN scenario configuration manually.
+::
+
+ sudo bash ./deploy.sh -b file://<path-to-opnfv-fuel-repo>/config/ -l devel-pipeline -p <your-lab-name> -s os-odl_l2-bgpvpn-ha -i file://<path-to-fuel-iso> -e
+
+With -e option the installer does not launch environment deployment, so
+a user can do some modification before the scenario is really deployed.
+
+Another interesting option is the -f option which deploys the scenario using an existing Fuel host.
