Lab Objective:
The objective of this lab exercise is for you to learn and understand how to configure VTP server and client modes on Cisco Catalyst Switches. By default, all Cisco switches are VTP server devices.
Lab Purpose:
Configuring VTP client and server modes is a fundamental skill. VLANs are configured on VTP servers and VTP clients receive VLAN information from the VTP servers in the same VTP domain. VLAN sharing is possible by using a trunk between the switches. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure VTP client and server modes.
Certification Level:
This lab is suitable for both CCENT and CCNA certification exam preparation.
Lab Difficulty:
This lab has a difficulty rating of 5/10.
Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 15 minutes.
Lab Topology:
Please use the following topology to complete this lab exercise:
Task 1:
In preparation for VLAN configuration, configure a hostname on the switches and routers as depicted in the topology. Keep in mind that the default mode of operation of Cisco Catalyst Switches is VTP server mode. Remember to use a crossover cable between the switches.
Task 2:
Configure and verify Sw1 as a VTP server switch and configure Sw2 as a VTP client switch. Both switches should be in the VTP domain named CISCO.
Task 3:
Configure and verify FastEthernet0/1 between Sw1 and Sw2 as an 802.1Q trunk.
Task 4:
Configure and verify VLANs 10 and 20 on Sw1 with the names provided above. Assign FastEthernet0/2 on both Sw1 and Sw2 to VLAN10. This interface should be configured as an access port.
Task 5:
Configure R1 and R3 FastEthernet0/0 interfaces with the IP addresses 10.0.0.1/28 and 10.0.0.3/28, respectively. Test connectivity via your VLANs by pinging R1 from R3, and vice versa.
Configuration and Verification
Task 1:
Switch#config t Enter configuration commands, one per line. End with CTRL/Z. Switch(config)#hostname Sw1 Sw1(config)# Switch#config t Enter configuration commands, one per line. End with CTRL/Z. Switch(config)#hostname Sw2 Sw1(config)# Router#config t Enter configuration commands, one per line. End with CTRL/Z. Router(config)#hostname R1 R1(config)# Router#config t Enter configuration commands, one per line. End with CTRL/Z. Router(config)#hostname R3 R3(config)#
Task 2:
NOTE: By default, Cisco switches are VTP servers so no configuration is necessary for server mode on Sw1. This can be verified using the show vtp status command. However, you do need to configure the domain.

Task 3:
NOTE: Some Cisco switches default to 802.1q trunking so no explicit configuration is required. The 2960 Switch (used in the exam) is set to dynamic auto so you will have to set at least one side to trunk.
