It then verifies the reachable time is betw=een 5 and 15 seconds (i.e. the valid range for the randomized reachable tim=e derived from a 10-second configured value).My concern is that the test might result in a false failure if the randomiz=ed reachable time value is close to 15 seconds, and there is a delay betwee=n when the reachable time for the entry is reached, and when the NUT receiv=es the next echo request from the TN.For example, if the randomized reachable time is 14.8 seconds:* At 0 seconds, the entry on the NUT is resolved* At 14.8 seconds, the reachable time is reached and the entry enters STALE state* At 15.3 seconds (say) the NUT receives the next echo request from the TN, sends an echo reply, and the entry enters DELAY state.* At 20.3 seconds, the entry enters PROBE state and the NUT sends the next NS.In this case, the test would calculate a reachable time of 15.3 seconds and= fail. Yet the NUT derived the randomized value correctly.Does the test account for the time that the ND entry on the NUT is in STALE= state? That is, does it account for the time between when the reachable ti=me expires and the next echo reply is sent?Thanks in advance,Peter HuntSoftware EngineerNokia S&S630_2.html (attatchment)(tag is disabled)
