Re: VTP Server and Transparent

Good Afternoon Marko,

Again, the question was vague, and he clarified, which I asked him to.

With Narbik response he was saying if a server with a virtual switch
inside, is set to root for the vlans, you can configure on the switch
and configure root guard or bpdu guard, filter, on the port that the
switch is connected to, to prevent superior BPDU received on the port.

Regards,
John
