E.4. Using the Native VLAN on a Trunked Interface

If a trunked interface or bond has a network on the native VLAN, the IP addresses are assigned directly to the bridge and there will be no VLAN interface.
For example, if the External network is on the native VLAN, a bonded configuration looks like this:
  - type: ovs_bridge
    name: {get_input: bridge_name}
    dns_servers: {get_param: DnsServers}
      - ip_netmask: {get_param: ExternalIpSubnet}
      - ip_netmask:
        next_hop: {get_param: ExternalInterfaceDefaultRoute}
      - type: ovs_bond
        name: bond1
        ovs_options: {get_param: BondInterfaceOvsOptions}
          - type: interface
            name: nic3
            primary: true
          - type: interface
            name: nic4


When moving the address (and possibly route) statements onto the bridge, remove the corresponding VLAN interface from the bridge. Make the changes to all applicable roles. The External network is only on the controllers, so only the controller template requires a change. The Storage network on the other hand is attached to all roles, so if the Storage network is on the default VLAN, all roles require modifications.
