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.
+BGPVPN blueprint at `Neutron Extension for BGP Based VPN <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, as well as a unique
definition of the related semantics. The BGPVPN framework supports a backend
