Nice, excellent explanation. Port security is a good suggestion. But I think that you overlook (deliberately?) the human factor. In your scenario someone would have to have physical access to a router/switch in order to attach the device. Or could the attacker simply connect the device to any functioning network port in a building? I don't think so, but I was wandering what your thoughts might be.

Hello Keith. Nice video, but i wonder why you propose port-security as defense mechanism against this attack, which seems to be a basic and broad security measure rather than DHCP Snooping, which is made to target this specific issue?

Keith, I am confused with manual pruning and vtp pruning concept. My understanding is that "switchport trunk allowed vlan" command will control (allow or block) all Vlan traffic whether it is uni-cast, broadcast or multicast where as VTP Pruning and Switchport trunk Pruning vlan command can only control(allow or Block) the multicast, broadcast and unknown uni-cast  but not the normal Uni-cast. I mean the dynamic VTP pruning can only prune the multicast and broadcast traffic but they can not prune the uni-cast traffic for vlan 2 even if we are using the " switchport trunk pruning vlan 2" under the trunk interface.  Am I correct? Thanx in advance :)
