Hi guys,
To Simon,
According to software configuration guide of 3550
Forward-delay timer - Determines how long each of the listening and learning
states last before the interface begins forwarding.
So if we set 7 or 8, then that will make the total delay time to 20 or 21
seconds,
listen stage - 7 seconds (forward-delay)
learning stage - 7 seconds (forward-delay)
reconfiguration stage - 6 seconds (max-age)
To Javier,
Honestly, I would like to clarify the original question as well cause I am
still trying to figure out the accurate requirement of it. But snapshot
routing can be used not only just dial-up link I think.
Cheers~
