It's actually not clear to me what the failure mode is here. If you attach two routers to a subnet and then have routes setup to point to one router for some subnets and the rest to another, are you saying that traffic fails to be forwarded to the correct subnet due to the flows?

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1447227 Title: Connecting two or more distributed routers to a subnet doesn't work properly Status in neutron: Incomplete Bug description: DVR code currently assumes that only one router may be attached to a subnet but this is not the case. OVS flows for example will not work correctly for E/W traffic as incoming traffic is always assumed to be coming from one of the two routers. The simple solution is to block the attachment of a distributed router to a subnet already attached to another distributed router.
