Bug description:
  [Impact]
  Stumbled upon an issue where removing a DVR HA router interface renders all other subnets connected to that router to stop routing. VMs can't reach the HA port (IP) of the router (ping).

  Worked around this by:
  openstack router set --disabled <ROUTER>
  openstack router set --enable <ROUTER>

  This has happened more than once in the current deployment
   - cloud:bionic-stein
   - neutron 2:14.0.4-0ubuntu1~cloud1

  [Test Case]
  TBD

  [Where problems could occur]
  TBD
