Yes, I meant symmetric not synchronous :) I'm not sure how symmetric routing can be achieved without the use of BGP. As has been discussed asymmetric routing will still work and isn't the worst thing in the world. I have the RFE to add fixed IP host route announcements here https://bugs.launchpad.net/neutron/+bug/1585770. BGP announcements are gated on having https://bugs.launchpad.net/neutron/+bug/1557290 fixed. I wouldn't gate the fast-exit work on BGP, even though the BGP changes aren't too tricky.

https://bugs.launchpad.net/neutron/+bug/1557290 needs more attention if we are to have the BGP announcements. Without it, the L3 agent won't setup the FIP namespace to route properly and packets will just black-hole when they hit the FIP namespace.

My hope is to be able to pursue both fast-exit and BGP independently since they really don't have to be tied together. I'll make a push on the BGP announcements as soon as https://bugs.launchpad.net/neutron/+bug/1557290 is fixed.
