VTP version 2 and Transparent Switches

Hi,

on the Catalyst 6500 IOS Cofiguration Guide there're the following sentences:

http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/12111bex/swcg/vtp.htm

on page 7-2 (pdf):

http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/12111bex/swcg/vtp.htm#xtocid3

"However, in VTP version 2, transparent network devices do forward VTP advertisements that they receive out their trunking LAN ports."

on page 7-3 (pdf):

http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/12111bex/swcg/vtp.htm#xtocid5

"VTP version 2 forwards VTP messages in transparent mode, without checking the version."

- With a switch configured with VTP version 2 and VTP mode transparent the VTP advertisements are forwarded or not ?

Thanks in advance

Re: VTP version 2 and Transparent Switches

I think,the first statement you cited dictates that,in VTP version 2,network devices configured as transparent mode will just forward VTP information out the trunking port without any processing.

The "transparent" here means network devices will not engage in the VTP domain information advertisement.

The second statement you cited dictates that,in VTP version 2,VTP messages are forwarded in transparent mode.It's just the same as what the first statement points out.

In fact,a switch configured as VTP transparent mode will forward VTP advertisements,whatever version of VTP is configured.
