John,

O believe you misunderstood "server" in this context. Don was using
"server" to refer to "the switch configured as VTP server", not a PC
attached to the switch.

Keep in mind that there are no PCs and servers currently in the CCIE lab.

@Narbik Why do you say the root guard would be needed here?
