parameters:
  ServiceNetMap:
    default: {}
    description: Mapping of service_name -> network name. Typically set
                 via parameter_defaults in the resource registry.  This
                 mapping overrides those in ServiceNetMapDefaults.
    type: json
  DefaultPasswords:
    default: {}
    type: json
  RoleName:
    default: ''
    description: Role name on which the service is applied
    type: string
  RoleParameters:
    default: {}
    description: Parameters specific to the role
    type: json
  EndpointMap:
    default: {}
    description: Mapping of service endpoint -> protocol. Typically set
                 via parameter_defaults in the resource registry.
    type: json
  NeutronEnableL2Pop:
    type: string
    description: >
        Enable/disable the L2 population feature in the Neutron agents.
    default: "False"
  NeutronBridgeMappings:
    description: >
      The OVS logical->physical bridge mappings to use. See the Neutron
      documentation for details. Defaults to mapping br-ex - the external
      bridge on hosts - to a physical name 'datacentre' which can be used
      to create provider networks (and we use this for the default floating
      network) - if changing this either use different post-install network
      scripts or be sure to keep 'datacentre' as a mapping network name.
    type: comma_delimited_list
    default: "datacentre:br-ex"
  NeutronTunnelTypes:
    default: 'vxlan'
    description: |
        The tunnel types for the Neutron tenant network.
    type: comma_delimited_list
  NeutronAgentExtensions:
    default: "qos"
    description: |
        Comma-separated list of extensions enabled for the Neutron agents.
    type: comma_delimited_list
  NeutronEnableDVR:
    default: False
    description: |
      Enable support for distributed routing in the OVS Agent.
    type: boolean
  NeutronEnableARPResponder:
    default: false
    description: |
      Enable ARP responder feature in the OVS Agent.
    type: boolean
  MonitoringSubscriptionNeutronOvs:
    default: 'overcloud-neutron-ovs-agent'
    type: string
  NeutronOVSFirewallDriver:
    default: ''
    description: |
      Configure the classname of the firewall driver to use for implementing
      security groups. Possible values depend on system configuration. Some
      examples are: noop, openvswitch, iptables_hybrid. The default value of an
      empty string will result in a default supported configuration.
