I think we should do just enough of this for the fast exit rfe [1] and leave the rest of this for another time.

"Fast-exit" DVR (https://bugs.launchpad.net/neutron/+bug/1577488) is an example of a use case where a framework for providing this information inside Neutron would be useful. With the Mitaka release BGP dynamic routing functionality was added to Neutron. BGP dyanmic routing exposes the concept of bindings between networks and BGP processes, which can provide the information described above. However, this is not a generic approach that supports other routing providers such as IPv6 proxy ND, OSPF, or other routing technology. What is needed is a framework that allows Neutron to ask whether there is a mechanism operating on an external or provider network that is handling routing traffic. To this end I'm proposing the creation of a simple, yet generic framework in Neutron that allows any number of "routing providers" to be registered with Neutron. Each routing provider is able to answer the question "do you route to next-hops on network X?". Among other things, this answer allows fast-exit DVR to be enabled dynamically based on whether appropriate routing is in place without placing more config file burden on operators or having tenants set attributes on a router to get fast-exit treatment.
