Lab Objective:
The objective of this lab exercise is for you to learn and understand how to configure VTP Transparent mode on Cisco Catalyst Switches. By default, all Cisco switches are VTP server devices.
Lab Purpose:
VTP Transparent mode configuration is a fundamental skill. VLANs configured on a switch in VTP Transparent mode are not automatically propagated to other switches within the same VTP domain as would be done by a VTP server. Switches configured in VTP Transparent mode use a trunk to forward traffic for configured VLANs to other switches. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure VTP Transparent mode.
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 switches 1 and 2 and routers 1 and 3 as illustrated in the topology.
Task 2:
Configure and verify Sw1 and Sw2 in VTP Transparent mode. Both switches should be in the VTP domain named CISCO. Remember that switches must be in the same VTP domain to share VLAN information via a trunk.
Task 3:
Configure and verify FastEthernet0/1 between Sw1 and Sw2 as an 802.1q trunk.
Task 4:
Configure and verify VLANs 2010 and 2030 on Sw1 with the names provided above. Assign FastEthernet0/2 on Sw1 to VLAN2010 as an access port. Configure and verify VLANs 2010 and 2040 on Sw2 with the names provided above. Assign FastEthernet0/2 on Sw2 to VLAN2010 as an access port.
Task 5:
Configure R1 and R3 FastEthernet interfaces with the IP addresses 10.0.0.1/28 and 10.0.0.3/28, respectively. Test VLAN connectivity by pinging between R1 and R3.

Task 3:
NOTE: Some Cisco switches default to 802.1q trunking so no explicit configuration is required. This ISN’T the case for the 2960 Switch, which is used in the exam.

NOTE: Default switches configured for VTP Transparent mode do not exchange VLAN information. You can see in the output above that VLAN2030 on Sw1 is not propagated to Sw2, and VLAN2040 on Sw2 is not propagated to Sw1. In Transparent mode, all VLANs must be manually configured on all switches.

It seems that it was my wrong as using PT and not permits vlan numbers above 1005.
Me too.
