When I try it, I see 11 seconds as the minimum based on your other
configuration values. According to this definition from the spec, 11
seconds is correct based on the max age you have configured:
2 × (Bridge_Forward_Delay – 1.0 seconds) >= Bridge_Max_Age
If you bring the max age down to six seconds, you'll get a four second
forward delay.
I also wonder why it must be 4-30 seconds. Linux bridge supports setting

It's defined that way in the 802.1D specification.
