Public bug reported:

As a result of debugging issues reported in
https://bugs.launchpad.net/neutron/+bug/1818614 I found an issue with
functional tests:

test_dvr_ha_router_failover_with_gw,
test_dvr_ha_router_failover_without_gw,
test_dvr_ha_router_failover_with_gw_and_floatingip

from module neutron.tests.functional.agent.l3.test_dvr_router are
broken.


First thing which is wrong there is fact that those tests creates 2 independent routers on 2 agents. It's not one router in "master" and "standby" mode. Please check in https://github.com/openstack/neutron/blob/68fd13af40ce2752d2919ca569d3d3fe00ff6444/neutron/tests/functional/agent/l3/test_dvr_router.py#L1503

Second issue is that it assumes that always router on agent1 will be
"master" and that may be different sometimes as it depends on keepalived
negotiations.
