Finally, VTP advertisements are multicasts that are not sent out every port on the switch. They are actually sent out of trunk ports only. There are 3 types of VTP advertisements; summary, subset, and client.
Summary Advertisements are transmitted by VTP servers
every 5 minutes, or upon a change in the VLAN
database. Information included in the summary
- VTP domain name and version
- Configuration revision number
- MD5 hash
- Number of subset advertisements that will follow this advertisement
Subset Advertisments tell whether a vlan has been created, deleted, activated, or suspended; and will give the name, MTU, and type of VLAN.
Client advertisements are actually clients requesting vlan information. A server will respond to this request with a summary and subset advertisement.
