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.

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

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
