17. Customizing external network vlan

If network-isolation is used in the deployment, tripleo-quickstart will, by default, add a NIC on the external vlan to the undercloud, <https://github.com/openstack/tripleo-quickstart/blob/master/roles/tripleo/undercloud/templates/undercloud-install-post.sh.j2#L88>. When working with a baremetal overcloud, the vlan values must be customized with the correct system-related values. The default vlan values can be overwritten in a settings file passed to triple-quickstart as in the following example:

undercloud_networks:
  external:
    address: 10.0.7.13
    netmask: 255.255.255.192
    device_type: ovs
    type: OVSIntPort
    ovs_bridge: br-ctlplane
    ovs_options: '"tag=102"'
    tag: 102
