Important Considerations
■
If the probability of losing configuration messages is high, 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 is 1 – 10, the available
range is constrained by the following inequality:
stpMaxAge >= 2 x (stpHelloTime + 1 second)
