| StorageAllocationPools | The allocation pool for the Storage network in a tuple format | |
| StorageMgmtAllocationPools | The allocation pool for the Storage Management network in a tuple format | |
| TenantAllocationPools | The allocation pool for the Tenant network in a tuple format | |
| ExternalAllocationPools | The allocation pool for the External network in a tuple format | |
| InternalApiNetworkVlanID | The VLAN ID for the Internal API network | 200 |
| StorageNetworkVlanID | The VLAN ID for the Storage network | |
| StorageMgmtNetworkVlanID | The VLAN ID for the Storage Management network | |
| TenantNetworkVlanID | The VLAN ID for the Tenant network | |
| ExternalNetworkVlanID | The VLAN ID for the External network | |
| ExternalInterfaceDefaultRoute | The gateway IP address for the External network | 10.1.2.1 |
| ControlPlaneDefaultRoute | Gateway router for the Provisioning network (or Undercloud IP) | ControlPlaneDefaultRoute: 192.0.2.254 |
| ControlPlaneSubnetCidr | CIDR subnet mask length for provisioning network | ControlPlaneSubnetCidr: 24 |
| EC2MetadataIp | The IP address of the EC2 metadata server. Generally the IP of the Undercloud. | EC2MetadataIp: 192.0.2.1 |
| DnsServers | Define the DNS servers for the Overcloud nodes. Include a maximum of two. | DnsServers: ["8.8.8.8","8.8.4.4"] |
| BondInterfaceOvsOptions | The options for bonding interfaces | BondInterfaceOvsOptions:"bond_mode=balance-slb" |
| NeutronFlatNetworks | Defines the flat networks to configure in neutron plugins. Defaults to "datacentre" to permit external network creation | NeutronFlatNetworks: "datacentre" |
| NeutronExternalNetworkBridge | An Open vSwitch bridge to create on each hypervisor. Typically, this should not need to be changed. | NeutronExternalNetworkBridge: "''" |
| NeutronBridgeMappings | The logical to physical bridge mappings to use. Defaults to mapping the external bridge on hosts (br-ex) to a physical name (datacentre). You would use this for the default floating network | NeutronBridgeMappings: "datacentre:br-ex" |
| NeutronPublicInterface | Defines the interface to bridge onto br-ex for network nodes | NeutronPublicInterface: "eth0" |
| NeutronNetworkType | The tenant network type for Neutron | NeutronNetworkType: "vxlan" |

| NeutronTunnelIdRanges | Ranges of GRE tunnel IDs to make available for tenant network allocation | NeutronTunnelIdRanges "1:1000" |
| NeutronVniRanges | Ranges of VXLAN VNI IDs to make available for tenant network allocation | NeutronVniRanges: "1:1000" |
| NeutronEnableTunnelling | Defines whether to enable or disable tunneling in case you aim to use a VLAN segmented network or flat network with Neutron. Defaults to enabled | |
| NeutronNetworkVLANRanges | The neutron ML2 and Open vSwitch VLAN mapping range to support. Defaults to permitting any VLAN on the datacentre physical network. | NeutronNetworkVLANRanges: "datacentre:1:1000" |
| NeutronMechanismDrivers | The mechanism drivers for the neutron tenant network. Defaults to "openvswitch". To specify multiple values, use a comma-separated string | NeutronMechanismDrivers: openvswitch,l2population |
