Enabling VTP Version 2
VTP version 2 is disabled by default on VTP version 2-capable network devices. When you enable VTP
version 2 on a network device, every VTP version 2-capable network device in the VTP domain enables
version 2.
VTP version 1 and VTP version 2 are not interoperable on network devices in the same VTP domain.
Caution
Every network device in the VTP domain must use the same VTP version. Do not enable VTP version 2
unless every network device in the VTP domain supports version 2.
Note In a Token Ring environment, you must enable VTP version 2 for Token Ring VLAN switching to
function properly on devices that support Token Ring interfaces.
To enable VTP version 2, perform this task:
Command
Step 1
Router(config)# vtp version {1 | 2}
Router(config)# no vtp version
Step 2
Router# show vtp status
This example shows one way to enable VTP version 2:
Router# configure terminal
Router(config)# vtp version 2
V2 mode enabled.
Router(config)#
This example shows how to enable VTP version 2 with any release:
Router# vtp version 2
V2 mode enabled.

Router# show vtp status | include V2
