Ho Hoang, No, this isn't correct at all. Of course, when you move the tolerance back to 1500 ms the keepalive timer should go back to 375 ms, otherwise the tolerance in practice remains at 500 ms. The same is true for the last change. Internally, tolerance is 4 * keepalive_intv, so if this one is wrong, the tolerance also becomes wrong.
