This section decribes how to configure Neutron configuration files to enable the networking-ansible ML2 driver and configure switch devices that will be managed by networking-ansible.
Configure type_drivers and mechanism_drivers and network_vlan_ranges.
Add
vlan
totype_drivers
,ansible
tomechanism_drivers
, and define thenetwork_vlan_range
that will be used by the openstack networks that use this driver.[ml2] type_drivers = vlan mechanism_drivers = ansible [ml2_type_vlan] network_vlan_ranges = physnet1:1000:1099
- Do not remove other values from these comma delimited lists if there are are already values present. Append a comma and your value to the list.
- physnet1 is an identifier configured in the bridge_mapping TODO(radez) doc ref to bridge_mapping
- the VLAN range (1000:1099 in this example) is provided by the switch administor. This range is the VLAN IDs assigned by Neutron when a network is created.
Add a section for each switch device that will be managed by networking-ansible.
Create a section for each host with a section name prefixed by
ansible:
in/etc/neutron/plugins/ml2/ml2_conf.ini
.[ansible:myhostname] ansible_network_os=junos ansible_host=10.10.2.250 ansible_user=ansible ansible_pass=password
- myhostname is an arbitrary internal identifier used only in ironic’s link_local_information.
- ansible_network_os is a valid Ansible Networking value to indicate switch type. Tested with networking-ansible: openvswitch, junos Untested but valid with networking-ansible: eos, nxos See contributor/provider for more information.
- ansible_host is the IP address or hostname used to connect to the switch.
- ansible_user username of the credentials used to connect to the switch.
- ansible_pass password of the credentials used to connect to the switch.
Additional available parameters:
ansible_ssh_private_key_file=/path/to/ansible-ssh manage_vlans=True
- ansible_ssh_private_key_file can be used as an alternative to ansible_pass to use ssh key authentication instead of password authentication.
- manage_vlans is optional and defaults to True. Set this to False for a switch if networking-ansible should not create and delete VLANs on the device.
Restart the Neutron API service
$ service neturon-server restart
