Overview
VLANs and VTP configuration are essential for efficient and scalable network management in switched environments. VTP implies VLAN management by enabling automatic propagation of VLAN configurations across interconnected switches. It reduce administrative overhead and ensuring consistency.

Case Studies and Requirements:
MTech Networks, a mid size enterprise, wants to segment its network using VLANs to improve security and manageability. They also need centralized VLAN management using VTP to synchronize VLAN configurations across switches. As a Network Engineer you need to implement the network topology, configure VLANs, and verify their propagation.
Technologies Implemented:
Topology Design : Create a topology with 5 switches and connect in a triangle to ensure redundancy. Draw appropriate links and label them.
Trunk Links: Identify and configure trunk links between the switches to allow VLAN traffic.
VTP Configuration: Choose one switch to act as the VTP Server and others as clients.
VLAN Configuration: Configure VLANs only on the VTP Server.
VLAN Verification: Save configuration on the VTP Server. Verify VLAN propagation by checking VLANs on other switches.
VTP Configuration steps:
Configure trunk links
Switch>en
Switch#configure terminal
Switch(config)#hostname MTech-S1
MTech-S1(config)#interface range fastEthernet 0/1-2
MTech-S1(config-if-range)#switchport mode trunk
Set VTP Server
MTech-S1(config)#VTP mode server
MTech-S1(config)#VTP domain cisco.com
MTech-S1(config)#VTP Password cisco
MTech-S1(config)#VTP version 2
Set VTP Clients
MTech-S3(config-if-range)#VTP mode client
MTech-S3(config)#VTP domain cisco.com
MTech-S3(config)#VTP password cisco
MTech-S3(config)#VTP version 2
Create VLANs
MTech-S1(config)#Vlan 10
MTech-S1(config-vlan)#name IT
MTech-S1(config)#vlan 20
MTech-S1(config-vlan)#name HR
MTech-S1(config-vlan)#vlan 30
MTech-S1(config-vlan)#name FIN
MTech-S1(config-vlan)#vlan 40
MTech-S1(config-vlan)#name AD
MTech-S1(config-vlan)#vlan 50
MTech-S1(config-vlan)#name CS
Save Configuration
MTech-S1(config-vlan)#do write
Verify VLAN Propagation
Outcome
Upon successful implementation, VLANs will propagate automatically to all VTP client switches. The network segmented into IT, HR and Finance departments for enhanced management. Trunk links ensure VLAN traffic flows between switches.
