Lab 16:
Restricting VLANs on Trunks and changing the VTP version
Lab Objective:
The objective of this lab exercise is for you to learn and understand how to restrict VLANs traversing trunks. By default, all VLANs are allowed to traverse trunks.
Lab Purpose:
VLAN trunk restriction is a fundamental skill. By default, all VLANs traverse trunks. However, in some cases, this may result in unnecessary VLANs being propagated, and may pose a security risk. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to restrict VLANs traversing trunks.
Certification Level:
This lab is suitable for CCNA certification exam preparation
Lab Difficulty:
This lab has a difficulty rating of 7/10
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 switches 1 and 2 as illustrated in the topology.
Task 2:
Configure and verify Sw1 and Sw2 as VTP Transparent switches. Both switches should be in the VTP domain named CISCO. Configure the switches to use legacy VTP version 1. Configure FastEthernet0/1 as a trunk between switches Sw1 and Sw2.
Task 3:
Verify your VLAN configuration on either switch Sw1 or Sw2 and ensure they are identical.
Task 4:
Allow only VLAN 2040 to traverse the trunk link on switch Sw1 and verify your configuration.
