|
| 481 |
+The configuration for using the Linux Bridge ML2 driver is fairly |
|
| 482 |
+straight forward. The Linux Bridge configuration for DevStack is similar |
|
| 483 |
+to the :ref:`Open vSwitch based single interface <single-interface-ovs>` |
|
| 484 |
+setup, with small modifications for the interface mappings. |
