Andy,
Excellent post !!!
One thing, though, you maybe forgot. In the documentation, it says that if
a tftp server isnt specified for the binding table, you must disable
conflict logging.
Wouldn't you lose points if that weren't done?
I know that dhcp will still work without that, but I think you'd lose points
anyway.
