VTP configuration
Topology:
S1 config: (VTP server)
hostname S1
VTP domain ccna
vtp mode server
S2 config: (VTP client)
hostname S2
VTP domain ccna
vtp mode client
- to verify , show vtp status
PS: all interfaces should be configured as trunk.
S1:
Switch(config)#int gi1/0/1
Switch(config-if)#switchport trunk encapsulation dot1q
Switch(config-if)#switchport mode trunk
S2:
Switch(config)#int gi1/0/1
Switch(config-if)#switchport trunk encapsulation dot1q
Switch(config-if)#switchport mode trunk
Switch(config)#int gi1/0/2
Switch(config-if)#switchport trunk encapsulation dot1q
Switch(config-if)#switchport mode trunk
S3:
Switch(config)#int gi1/0/1
Switch(config-if)#switchport trunk encapsulation dot1q
Switch(config-if)#switchport mode trunk
Lets test it:
we will create a vlan 55 on S1 (server) , and it should be configured via VTP on S2 which is the client:
S1(config)#vlan 55
S1(config-vlan)#name amigo
S1(config-vlan)#exit
S1(config)#exit
S1#
%SYS-5-CONFIG_I: Configured from console by console
S1#show vl
S1#show vlan br
S1#show vlan brief

and voila , vlan auto configured on S2.
S3 , will not have auto vlan configured because , its configured as vtp transparent.
