To function properly, Neutron requires that a user, role, and endpoint be created in Keystone. When executed from the controller node, the following commands will create a user called neutron in Keystone, associate the admin role with the neutron user, and add the neutron user to the service project:

    # source ~/adminrc
    # openstack user create --domain Default --password=neutron neutron
    # openstack role add --project service --user neutron admin

Create a service in Keystone that describes the OpenStack Networking service by executing the following command on the controller node:

    # openstack service create --name neutron 
    --description "OpenStack Networking" network

To create the endpoints, use the following openstack endpoint create commands:

    # openstack endpoint create --region RegionOne
     network public http://controller01:9696
    # openstack endpoint create --region RegionOne
     network internal http://controller01:9696
    # openstack endpoint create --region RegionOne
     network admin http://controller01:9696
