Ok, I'm suffering from a brain cloud at the moment. So, willing to suffer
the comic flames and arrows, I ask the following question:
Assume we have three switches: A, B, and C. A has a fast ethernet
connection to B and another to C. B and C are not directly connected. At
this point, these are
ISL and done deal-

If you use ISL, it will pass traffic only if it is destined for that VLAN. It
does frame tagging.
It won't pass unnecessary traffic.

In this case, though, both switches B and C are in the same VLAN, but I
wouldn't want traffic destined for C going down the trunk connected to B.
This would be a waste of time and bandwidth. I'm trying to determine if the
trunk will pass ALL traffic for that VLAN, or only VLAN traffic that is
ac
To answer your question, I believe the switch ports, whether trunked or not,
still forward based on the table of learned MAC-addresses.
Meaning that a VLANx packet, assuming the destination MAC address is already
learned, will only traverse the trunk port towards the valid destination.

Thank you! I've been trying to find the answer to that for a while now. I
don't have a way to test it on our production network or I would have simply
set it up and watched what happened. My bosses get a little upset when I
start playing with our corporate backbone switches just for the fun of
ice inside the trunk.
