  Software Config to drive os-net-config for a simple linux bridge.
parameters:
  ControlPlaneIp:

  {{network.name}}IpSubnet:
    default: ''
    description: IP address/subnet on the {{network.name_lower}} network
    type: string
  {{network.name}}InterfaceRoutes:
    default: []
    description: >
      Routes for the {{network.name_lower}} network traffic.
      JSON route e.g. [{'destination':'10.0.0.0/16', 'nexthop':'10.0.0.1'}]
      Unless the default is changed, the parameter is automatically resolved
      from the subnet host_routes attribute.

  {{network.name}}Mtu:
    default: {{network.mtu|default('1500')}}
    description: The maximum transmission unit (MTU) size(in bytes) that is
      guaranteed to pass through the data path of the segments in the
      {{network.name}} network.
    type: number
  {%- endfor %}
  ControlPlaneDefaultRoute:
    description: The default route of the control plane network. (The parameter
      is automatically resolved from the ctlplane subnet's gateway_ip attribute.)
    type: string
    default: 192.168.24.1
  ControlPlaneStaticRoutes:
    default: []
    description: >
      Routes for the ctlplane network traffic.
      JSON route e.g. [{'destination':'10.0.0.0/16', 'nexthop':'10.0.0.1'}]
      Unless the default is changed, the parameter is automatically resolved
      from the subnet host_routes attribute.
    type: json
  ControlPlaneSubnetCidr:
    default: ''
    description: >
      The subnet CIDR of the control plane network. (The parameter is
      automatically resolved from the ctlplane subnet's cidr attribute.)
    type: string
  ControlPlaneMtu:
    default: 1500
    description: The maximum transmission unit (MTU) size(in bytes) that is
      guaranteed to pass through the data path of the segments in the network.

    type: number
  DnsServers: # Override this via parameter_defaults
    default: []
    description: >
      DNS servers to use for the Overcloud (2 max for some implementations).
      If not set the nameservers configured in the ctlplane subnet's
      dns_nameservers attribute will be used.
    type: comma_delimited_list
  EC2MetadataIp:
    default: ''
    description: The IP address of the EC2 metadata server. (The parameter
      is automatically resolved from the ctlplane subnet's host_routes attribute.)
