Hi,
I suppose that daisy-chaining switches beyond 3 or 4 bridges is not
recommended, because I have never saw this in a reference design. I
also know the IEEE 802.1D recommendation of having no more than 7
bridges diameter with the default STP timers. However, can anyone
tell me WHY having a 7-8 bridge loop topology is such a bad idea in
practice after all, especially with RSTP, apart from possibly
degrading convergence time? I am not saying that this would be good,
I just want to clear the FUD. My understanding is that the
theoretical diameter is given by the Max Age value, hence we may have
a maximum diameter of 20.
Thanks,
Mihai
