All network devices in a VTP domain must run the same VTP version.
You must configure a password on each network device in the management domain when in secure
mode.
A VTP version 2-capable network device can operate in the same VTP domain as a network device
running VTP version 1 provided VTP version 2 is disabled on the VTP version 2-capable network
device (VTP version 2 is disabled by default).
Do not enable VTP version 2 on a network device unless all of the network devices in the same VTP
domain are version 2-capable. When you enable VTP version 2 on a network device, all of the
version 2-capable network devices in the domain enable VTP version 2.
In a Token Ring environment, you must enable VTP version 2 for Token Ring VLAN switching to
function properly.
When you enable or disable VTP pruning on a VTP server, VTP pruning for the entire management
domain is enabled or disabled.
The pruning-eligibility configuration applies globally to all trunks on the router. You cannot configure
pruning-eligibility separately for each trunk.
When you configure VLANs as pruning eligible or pruning ineligible, pruning eligibility for those
VLANs is affected on that router only, not on all network devices in the VTP domain.
VTPv1 and VTPv2 do not propagate configuration information for extended-range VLANs (VLAN
numbers 1006 to 4094). You must configure extended-range VLANs manually on each network
device.
If there is insufficient DRAM available for use by VTP, the VTP mode changes to transparent.
Network devices in VTP transparent mode do not send VTP Join messages. On Cisco 7600 series routers
with trunk connections to network devices in VTP transparent mode, configure the VLANs that are used
by the transparent-mode network devices or that need to be carried across trunks as pruning ineligible.
For information about configuring prune eligibility, see the
VLANs" section on page 10-11.
