Hi Arzhel,
I'm working on writing down required changes to our setup to introduce BGP routing in CloudVPS transport network (between the Neutron virtual router and the Core Router).
It would be great if you can write details of what you need from us, and a recommended procedure/timeline for doing the changes. Example of stuff I'm expecting:
* Neutron would need to use BGP protocol version X (I ignore this bit) * We can only recv x.x.x.x ranges, and not other ranges * we'd need to do the switch from static to BGP only on a concrete day * You need to use AS # NNN * Make sure protocol X is allowed in any firewalling for the session to be correctly established (or monitoring or whatever)
My idea is to merge your ideas/requirements with what Neutron docs say. The docs will end up here:

For now, let's assume everything will happen in codfw (in our codfw1dev deployment).
