+SDN VPN capabilities and usage
+================================
+The BGPVPN feature enables creation of BGP VPNs 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.
+
+Currently, in OPNFV only ODL is supported as a backend for BGPVPN. API calls are
+mapped onto the ODL VPN Service REST API through the BGPVPN ODL driver and the
+ODL Neutron Northbound module.
+
+Feature and API usage guidelines and example
+-----------------------------------------------
+
+For the details of using OpenStack BGPVPN API, please refer to the documentation
