Please. I create simple config. CBQ | class | | class1 class2 when rate of class1 is high for the rate of class2, finaly rate of class2 exceed the given. My experiments gives for example if class1 rate = 90Mbit and class2 rate = 10Mbit so actual rate of class2 can be from 11.4 to 12.5 ( and far more ). Thank you.
