Comment 1 for bug 1662546

this is problematic code:

_neutron_ovs_base_setup_bridge $INTEGRATION_BRIDGE

The full code:

function configure_ovs {
    if is_service_enabled df-controller ; then
        # setup external bridge if necessary
        check_dnat=$(echo $DF_APPS_LIST | grep "DNATApp")
        if [[ "$check_dnat" != "" ]]; then
            echo "Setup external bridge for DNAT"
            sudo ovs-vsctl add-br $PUBLIC_BRIDGE || true
        fi

        _neutron_ovs_base_setup_bridge $INTEGRATION_BRIDGE
        sudo ovs-vsctl --no-wait set bridge $INTEGRATION_BRIDGE fail-mode=secure other-config:disable-in-band=true
        if [ -n "$OVS_INTEGRATION_BRIDGE_PROTOCOLS" ]; then
            sudo ovs-vsctl set bridge $INTEGRATION_BRIDGE protocols=$OVS_INTEGRATION_BRIDGE_PROTOCOLS
        fi
    fi

    if [ -n "$OVS_MANAGER" ]; then
        sudo ovs-vsctl set-manager $OVS_MANAGER
    fi

    cd $_pwd
}
