|
|
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.
|

|
|
BondInterfaceOvsOptions
|
The options for bonding interfaces
|
BondInterfaceOvsOptions:"bond_mode=balance-tcp"
|
|
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. This defaults to "br-ex". Set to
"br-ex" if using floating IPs on native VLAN on bridge br-ex. Typically, this should not need to be changed.
|
NeutronExternalNetworkBridge: "br-ex"
|
|
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

The tunnel types for the neutron tenant network. To specify multiple values, use a comma separated string.
|
NeutronTunnelTypes: 'gre,vxlan'
|
|
NeutronTunnelIdRanges
|
Ranges of GRE tunnel IDs to make available for tenant network allocation
|
NeutronTunnelIdRanges "1:1000"
|
|

|
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'
|
