vtp clients affect on the rest of the network

Hi,

http://www.cisco.com/warp/customer/473/21.html#vtp_ts_cav

states that a vtp client with a higher revision number can bring down the rest of the network by replacing the vlans on the rest of the switches

However CCIE routing and switching Official exam cert guide 2nd edition page 40 states that a client or transparent cannot affect the network as it does not originate updates

Which is correct ?

Re: vtp clients affect on the rest of the network

this is correct.

if you have vtp1 running in your network and put a vtp2 enabled switch trunked into that network and the vtp2 only has vlan1, then you could lose all your vlans as a 'higher version' vtp2 will force the other switches to enable vtp2 if the can support it. (at that point, you've probably got what the vtp2 switch vlans are and may have lost what your vtp1 knew)

also, the ccie routing/switching is correct. a client/transparent does not originate updates.
