Lab 25 VTP

Objective

• To learn how to configure VTP domain on switches
• To understand the function of VTP domain.

Topology

Setting

PC0 and PC2 are in VLAN1, and PC1 and PC3 are in VLAN2.
The two Gig1/1 ports  on access layer switches are connected to the distribution layer switch.
The distribution layer switch has routing function.
IPs for computers have been configured.

Requirements

• Configure a VTP Domain
• Configure VTP Clients
• Configure the VTP server
• Configure VTP password

Steps

On Switch1

Switch(config)#interface gigabitEthernet 1/1
Switch(config-if)#switchport mode trunk
Switch(config-if)#exit
Switch(config)#vtp domain office1
Changing VTP domain name from NULL to office1
Switch(config)#vtp password aaa
Switch(config)#vtp mode client
Setting device to VTP CLIENT mode.
Switch(config)#

On Switch2

Switch#confi t
Switch(config)#interface gigabitEthernet 1/1
Switch(config-if)#switchport mode trunk
Switch(config)#vtp domain office1
Changing VTP domain name from NULL to office1
Switch(config)#vtp mode client
Setting device to VTP CLIENT mode.
Switch(config)#vtp password aaa
Setting device VLAN database password to aaa
Switch(config) #

On Switch0

Switch#confi t
Switch(config)#interface gigabitEthernet 0/1
Switch(config-if)#switchport mode trunk
Switch(config-if)#interface gigabitEthernet 0/2
Switch(config-if)#switchport mode trunk
Switch(config)#vtp domain office1
Changing VTP domain name from NULL to office1
Switch(config)#vtp password aaa
Switch(config)#vtp mode server
Device mode already VTP SERVER.
Switch(config)#

Test VTP

On Switch0

Switch(config)#vlan 2
Switch(config-vlan)#exit
Switch(config)#vlan 3
Switch(config-vlan)#

On Switch

Switch#show vlan
