external network overrides template

Network configuration overrides.

This is a consequence of using use_dhcp: true on the control plane interface of the controller.yaml. The Undercloud sets a specific route (not default) to the all-zeroes network, which overrides the default route on the External interface.

Assuming this is OSP-Director 7.1 or later, use the following in controller.yaml to use a static IP address on the control plane (which will not have a default route):

              # Assuming you want to keep br-ex as external bridge name
              name: {get_input: bridge_name}
              use_dhcp: true
              defroute: yes
