Configuring the ML2 plugin

The ML2 plugin has its own configuration file, which can be found at /etc/neutron/plugins/ml2/ml2_conf.ini. The LinuxBridge and Open vSwitch agents continue to rely on their respective configuration files, which were configured previously in this book.

To implement ML2 with the LinuxBridge agent based on prior configuration documented in earlier chapters, use the following configuration in /etc/neutron/plugins/ml2/ml2_conf.ini:

[ml2] 
type_drivers = local,flat,vlan
tenant_network_types = vlan
mechanism_drivers = linuxbridge

[ml2_type_flat]
flat_networks = physnet1

[ml2_type_vlan]
network_vlan_ranges = physnet1:30:33

[database]
connection = mysql://neutron:neutron@controller/neutron_ml2

[securitygroup]
firewall_driver = 
dummyValue

The firewall_driver parameter must be defined in the ML2 configuration to enable the securitygroup extension. However, the actual value set for firewall_driver in the ml2_conf.ini file is irrelevant. Each L2 agent configuration file...
