One more link showing the data flow if BGP (or other routing mechanism) is not made aware that the FIP gateway port can be used as the next-hop for a fixed IP. What you would get is asymmetric data flow where northbound traffic get DVR treatment, but southbound traffic still gets routed through the centralized router. Once this is in place, a quick patch can be made to neutron-dynamic-routing to get BGP announcements that use the FIP gateway as the next-hop.
