Technically, I have to agree with Robbie. I probably should have said
something more along the lines of "There are 2 ways to prevent unnecessary
broadcast and unknown traffic from transiting a trunk...".

Tim's original statement was "there are 2 ways to configure pruning...".
Tim, could that be stated another way, such as "there are 2 ways to remove
vlans from a trunk"?

Is it still technically pruning if you're allowing only specific VLANs
to transit a trunk link? I always thought of pruning as a process of
removing VLANs that are otherwise allowed on the link, which you have to
be running VTP to do (via the pruning mechanism).
Semantics, whee. :D
Cheers,
Robbie
