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.
