However, a switch running
VTPv1 propagates only VTP messages that have the same VTP domain as the domain
that is con?¬?gured on the local switch. VTP transparent mode switches that are using
VTPv1 drop VTP advertisements if they are not in the same VTP domain.
?– The extended-range VLANs are not propagated. So you must con?¬?gure extendedrange
VLANs manually on each network device.
?– The updates from a VTP server are not updated on a client if the client already has a
higher VTP revision number. In addition, the client does not propagate the VTP
updates to its downstream VTP neighbors if the client has a higher revision number
than that which the VTP server sends.
Recently Installed Switch Causes Network Problems
A newly installed switch can cause problems in the network when all the switches in your
network are in the same VTP domain, and you add a switch into the network that does not
have the default VTP and VLAN con?¬?guration.
If the con?¬?guration revision number of the switch that you insert into the VTP domain is
higher than the con?¬?guration revision number on the existing switches of the VTP domain,
your recently introduced switch overwrites the VLAN database of the domain with its own
VLAN database.
