Vlans will not stop all typres of broadcast storm.


So, perhaps I missed the earlier explanation, but why use switched
segments at all? if the purpose is to connect routers to routers putting
something that WILL FAIL in the middle is only going to increase your
labor costs later :(

So, for router-router links, GE doesn't have to mean switched...

Very true.  In fact, GE is even easier because part of the GE standard
for UTP requires it to be Auto-MDI-Sensing (MDI vs MDI-X is handled
automatically in ALL compliant GE/TP interfaces).  Thus, you can use
any eia-568[ab] cable, straight or crossed between them.  (Note, USOC
cables still won't work, it has to be 568a or 568b pairing)
