This is an alternative Neutron configuration for setting up Layer 2 and Layer 3 without using journaling.
Complete the following changes in the configuration files to enable the non-journal plug-in.
The following configuration lines must be available in
/etc/neutron/plugins/ml2/ml2_conf.ini. The mechanism driver must be
set to extreme_efa along with
[ml2] mechanism_drivers = openvswitch,extreme_efa,sriovnicswitch
The following configuration lines must be available in the
/etc/neutron/neutron.conf file for the L3 Service plug-in to be
[DEFAULT] service_plugins = extreme_l3_efa,efa_topology_plugin,trunk,segments
extreme_l3_efais an L3 Service Plug-in and is a replacement for the default L3 Service Plug-in (called
router). Only one of them should be used.
To enable L3 flavors with Extreme, service providers must be added to

Flavors require the default L3 Service Plug-in (called
