Comment 2 for bug 1716721

This is caused by a neutron subnetpool and gateway implementation.
The easiest way to reproduce is: "neutron -v subnet-create --no-gateway --use-default-subnetpool net3" or use compatible osc command.

Even though {"subnet": {"network_id": "e8a2c627-d296-4504-9e87-9f2a97dbaa89", "ip_version": 4, "gateway_ip": null, "use_default_subnetpool": true}} is passed to the neutron server, the created subnet has a gateway.
