Enable the Networking NW-ODL ML2 plugin¶

This section explains how to enable the Networking OpenDaylight (NW-ODL) Modular Layer 2 (ML2) plugin for Neutron in your deployment using the Neutron Salt formula, which can install the networking-odl package and enables Neutron to connect to the OpenDaylight controller.

To enable the NW-ODL ML2 plugin:

1. Log in to the Salt Master node.

2. Define the OpenDaylight plugin options in the cluster/<cluster_name>/openstack/init.yml file as follows:

   _param:
     opendaylight_service_host: <ODL_controller_IP>
     opendaylight_router: odl-router_v2 # default
     opendaylight_driver: opendaylight_v2 # default
     provider_mappings: physnet1:br-floating # default
   

3. In the cluster/<cluster_name>/openstack/control.yml file of your Reclass model, configure the Neutron server by including the system.neutron.control.opendaylight.cluster class and setting credentials and port of OpenDaylight REST API. For example:

   classes
   - system.neutron.control.opendaylight.cluster
   parameters:
     neutron:
       server:
         backend:
           rest_api_port: 8282
           user: admin
           password: admin
   

4. In the cluster/<cluster_name>/openstack/gateway.yml file of your Reclass model, include the following class:

   classes
   - service.neutron.gateway.opendaylight.single
   

5. In the classes/cluster/<cluster_name>/openstack/compute.yml file of your Reclass model, include the following class:

   classes
   - service.neutron.compute.opendaylight.single
   

6. Apply the configuration changes by executing the neutron state on all nodes with neutron:server, neutron:gateway, and neutron:compute roles:

   salt -I 'neutron:server' state.sls neutron
   salt -I 'neutron:gateway' state.sls neutron
   salt -I 'neutron:compute' state.sls neutron
