SDN VPN capabilities and usage
================================

The BGPVPN feature enables creation of BGP VPNs according to the OpenStack
BGPVPN blueprint <link>. 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. For the details of using the OpenStack
BGP VPN API, please refer to the documentation at <link>.

Currently, in OPNFV only ODL is supported as a backend for BGPVPN. The BGPVPN
API calls are mapped onto the ODL VPN Service REST API through the BGPVPN ODL
driver and the ODL Neutron Northbound module.
