+Activate OpenDaylight and VXLAN network segmentation
+----------------------------------------------------
+** Note: With the current release, the OpenDaylight option is experimental!**
+** Note: With ODL enabled, L3 features will no longer be available **
+The activation of ODL within a deployed Fuel system is a two part process.
+
+The first part involves staging the ODL container, i.e. starting the ODL container itself.
+The second part involves a reconfiguration of the underlying networking components to enable VXLAN tunneling.
+The staging of the ODL container works without manual intervention except for editing with a valid DNS IP for your system
+
+For the second part - the reconfiguration of the networking, the script <config_net_odl.sh> is provided as a baseline example to show what needs to be configured for your system system setup. Since there are many variants of valid networking topologies, this script will not be 100% correct in all deployment cases and some manual script modifications maybe required.
+
+39. Enable the ODL controller
+ssh to any of the OpenStack controllers and issue the following command as root user: </opt/opnfv/odl/stage_odl.sh>
+This script will start ODL, load modules and make the Controller ready for use.
+** Note: - The script should only be ran on a single controller (even if the system is setup in a High Availability OpenStack mode). **
+
+40. Verify that the OpenDaylight GUI is accessible
+Point your browser to the following URL: <http://{ODL-CONTROLLER-IP}:8181/dlux/index.html> and login:
+Username: Admin
+Password: Admin
+
+41. Reconfiguring the networking and switch to VXLAN network segmentation
+ssh to all of the nodes and issue the following command </opt/opnfv/odl/config_net_odl.sh> in the order specified below:
+a. All compute nodes
+b. All OpenStack controller nodes except the one running the ODL-controller
+c. The OpenStack controller also running the ODL controller
+
+This script will reconfigure the networking from VLAN Segregation to VXLAN mode.
