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?

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.
