I think what Gary is talking about is BGP and the Border Gateway API spec[1] in L2 GW repo.

Re: [openstack-dev] [Neutron] BGP support
Thanks for the pointers. Any reason why this is not part of the L2 gateway effort? I think that could be a natural place for this. The project name may be a bit misleading, but at the end of the day the Neutron tenant will have network connectivity irrespective if a neutron network is realized in a number of different places that are connected either via MPLS or BGP or any other protocol.
