** Description changed:
Scenario: Queens, DVR without L3 HA, distributed non-HA virtual router
(pubrouter), all subnets are attached to 2 different subnet pools, all
of them have one global address scope so DVR "fast exit" is triggered
(https://review.openstack.org/#/c/474007/), floating ips are not used,
snat is not enabled.

Note: (This setup uses routed provider networks so unit names correspond to
nodes that have connectivity to the right physnets, however, this is irrelevant
for this bug)
