So we will be creating the ports separately from the servers:

```sh
$ openstack port create --network "$INFRA_ID-network" --security-group "$INFRA_ID-master" --allowed-address ip-address=192.0.2.5 --allowed-address ip-address=192.0.2.6 --allowed-address ip-address=192.0.2.7 --tag openshiftClusterID="$INFRA_ID" "$INFRA_ID-bootstrap-port"

```
