VTP 

In Cisco Packet Tracer, VTP stands for VLAN Trunking Protocol. VTP is a Cisco proprietary protocol that facilitates the management and distribution of VLAN information across a network infrastructure. It allows for centralized management of VLANs, making it easier to configure and maintain VLANs consistently across multiple switches.

Here's how to use VTP in Cisco Packet Tracer:

• Build the network topology: Create the network topology by adding switches to the workspace and connecting them using appropriate interfaces.

• Enable VTP: Access the CLI (Command Line Interface) of each switch by double-clicking on it or selecting it and clicking on "CLI" in the toolbar. Enter the following commands:

enable

configure terminal

vtp mode server

vtp domain <domain-name>

vtp password <password>

• Replace <domain-name> with the desired VTP domain name, and <password> with the password to be used for VTP domain configuration. All switches within the same VTP domain should have the same domain name and password.

• Configure VLANs on the VTP server: On the VTP server switch, create the VLANs using the following command:

vlan <vlan-id>

name <vlan-name>

• Replace <vlan-id> with the desired VLAN ID and <vlan-name> with the desired VLAN name. Repeat this command for each VLAN you want to create.

• Configure VTP client switches: On the VTP client switches, configure them to operate in VTP client mode using the following commands:

enable

configure terminal

vtp mode client

vtp domain <domain-name>

vtp password <password>

• Replace <domain-name> and <password> with the same values used in Step 2.

• Connect switches using trunk links: Connect the switches using trunk links to enable VLAN information propagation across the network. To configure trunking, refer to the previous instructions provided for trunking configuration in Cisco Packet Tracer.

• Verify VTP configuration: Use the following command on any switch to verify the VTP configuration:

show vtp status

• This command displays the VTP domain, mode, and other relevant information.

By following these steps, you can use VTP in Cisco Packet Tracer to centrally manage and distribute VLAN information across your network infrastructure. Remember to save the configurations and verify the VTP status on each switch using the show vtp status command.

Note that Cisco Packet Tracer is a simulation tool, and certain advanced VTP features and functionalities may not be available or fully replicated within the tool. In real-world network environments, additional considerations and precautions should be taken when implementing VTP.

Here is an example of a set up VTP:

VTP Configuration:

Ena

Conf t

Feature vtp // Enables VTP

Vtp domain [NAME] // Set VTP domain name [NAME]

Vtp password cisco // We use cisco as example password, this could be anything

Vtp version 2

Vtp mode client                        

No shutdown

End

Ena

Sh vtp status
