Might be something wrong happening here https://opendev.org/openstack/tripleo-heat-templates/src/branch/stable/queens/docker/services/neutron-l3.yaml#L65

[chandan kumar (chkumar246)]

it happened due to bad cherry-pick https://review.opendev.org/c/openstack/tripleo-heat-templates/+/766336/2/docker/services/neutron-l3.yaml closing this one as invalid
