Important Considerations
■If the probability of losing configuration messages is h igh, shorten the
time to make the protocol more robust.
■If the probability of losing configuration messages is low, lengthen the
time to lower the overhead of the algorithm.
■The recommended Hello time is 2 seconds.
■Although the possible range for stpHelloTime i s 1 – 10, the available
range is constrained by the following inequ ality:
stpMaxAge >= 2 x (stpHelloTime + 1 seco nd)
