20 * OpenStack Neutron with the Open vSwitch plugin relies on a typical bridge configuration that
21 * consists of br-int (Integration Bridge), br-net (Network bridge), br-ex (External bridge).
23 * This class ensures that the bridges on each {@link Node}
24 * are correctly configured for OpenStack Neutron
