BN321 Assignment: Local Area Network Design and Implementation

This document presents a comprehensive Local Area Network (LAN) design and implementation, addressing IP addressing, subnetting, and network configurations. The assignment details a network architecture with multiple subnets, including labs, library, and classroom environments, using a 192.168.0.0/23 network. It demonstrates the allocation of IP addresses, subnet masks, and assignable ranges for each subnet. The solution includes router and switch configurations using Cisco Packet Tracer, showcasing the setup of VLANs, DHCP pools, and trunking. Configuration commands are provided for the router, including interface configurations, encapsulation, and IP address assignments, as well as DHCP exclusions and pools. Switch configurations are also detailed, covering VTP domain setup, VLAN creation, and interface configurations. The document provides screenshots of the network device configurations, offering a complete guide to the design and implementation of a local area network.

Configuration commands used for configuring the network in packet
tracer
Here we have used the two interface of the router i.e. fa 0/0 and fa0/1 and subdivided the interface for
creating a dhcp pool for each of the subnet. The configuration used for configuring the router and the
layer 3 switch is attached for reference below.
