Implementation of VLAN Segmentation, EtherChannel, DHCP, and NAT in a Cisco Enterprise Network

This project focuses on the design and implementation of a Cisco Enterprise Network using GNS3 simulation. The network consists of two routers (R1 and R2), three Cisco IOSvL2 switches (S1, S2, and S3), and two client PCs connected through VLAN segmentation.

The project implements VLAN 150 and VLAN 200 to separate network traffic and improve security. EtherChannel using LACP is configured between the core switch and access switches to provide redundancy and increase bandwidth. DHCP services are configured on the routers to automatically assign IP addresses to client devices, while NAT (Network Address Translation) enables Internet connectivity through external network interfaces.

The network topology was tested using various verification commands, VLAN validation, EtherChannel status monitoring, and end-to-end connectivity testing. This project demonstrates practical enterprise networking concepts including network segmentation, redundancy, dynamic IP allocation, and Internet access configuration using Cisco technologies.
