Ironic Flat Networking

This method carries security risks! Nodes all share the same L2 and L3 domain with the controller, so you must implement security methods outside the scope of Openstack.

To use a single network for API, provisioning, and tenant networking, you'll need the following configuration options in your defaults.yml

When configuring your network, make sure to set the network-type to 'flat'

  - name: physnet1
    bridge_name: br-physnet1
    external_interface: veth-internalb
    network_type: 'flat'
      cidr: '' # cidr of your netblock
        - start: ''
          end: ''

You'll also need to override two defaults

ironic_provisioning_network: sharednet1
neutron_tenant_network_types: flat
