The functional test test_gateway_chassis_with_bridge_mappings is written in a way that exercises something that is just not feasible in the API. It essentially tries to do:

  openstack router set router1 --external-gateway public_net1
  openstack router set router1 --external-gateway public_net2
  openstack router set router1 --external-gateway public_net3

In reality, it should be doing:

  openstack router set router1 --external-gateway public_net1
  openstack router unset router1 --external-gateway

  openstack router set router1 --external-gateway public_net2
  openstack router unset router1 --external-gateway

  openstack router set router1 --external-gateway public_net3
  openstack router unset router1 --external-gateway

The test is located at:

One way to run it is by invoking the command on a 'stacked' system:

  cd /opt/stack/networking-ovn && \
  tox -e dsvm-functional -- \
  networking_ovn.tests.functional.test_router.TestRouter.test_gateway_chassis_with_bridge_mappings
