Summary advertising ? VTP

[Stefan Marcin]

Hello guys, I have a question regarding VTP. In curriculum there is written Summary Advertisement is sent every 300 seconds and every time a VLAN database change occurs.

Question - When change occurs only on one VLAN - summary advert with only ONE Subset advert is sent defining that change on specific VLAN - or completely everything is sent out ?

Question2 -  After 300 seconds - everything is sent to neighbouring switches I mean whole database ?

Hello Stefan
This is one of those I can never remember so I have documented it as I understand it.

Question1
Summary includes (vtp version , domain name, configuration revision number, time stamp) every 300 secs
Subset includes the specific changes

Question2 - every 300 secs
Summary includes (vtp version , domain name, configuration revision number, time stamp)

Also - If a summary is received on a switch with a higher revision number the receiving switch can initiate a advertisement request for more information.
