Introduction

This project presents a detailed design of a network for a company with two branch offices and a central server, focusing on ensuring efficient communication, scalability, and security. The network includes VLANs, inter-VLAN routing, DHCP, DNS, HTTP services, and uses RIP for dynamic routing.

Network Design

Topology Diagram

A comprehensive topology diagram illustrates the network's structure, showcasing the connections between branches and the central server.

Justification of Topology

The chosen topology supports efficient communication and centralized management. It includes VLANs for each department, dynamic routing through RIP, and firewalls for security.

Configuration Details

VLAN Configuration

VLANs are configured for each department to improve network performance and isolate traffic.

InterVLAN Routing

InterVLAN routing is set up using sub-interfaces on central routers, enabling communication between different VLANs.

DHCP Configuration

DHCP servers are configured to dynamically allocate IP addresses, simplifying network management.

RIP Protocol

RIP is employed to dynamically share routing information between the branches and the central server.

Firewalls

Firewalls are implemented on DHCP and HTTP servers to restrict unauthorized access.

Routing Optimization

RIP is used for its simplicity and effectiveness in smaller networks, ensuring updated routing information across the network.

Testing and Validation

Functional Testing

Tests include DHCP functionality, inter-VLAN communication, WLAN connectivity, and DNS/HTTP services.

Simulation

Simulations for HTTP, DNS, and ICMP validate network performance and reliability.

Conclusion

The project successfully demonstrates the design and implementation of a robust network infrastructure, with recommendations for future improvements like OSPF and intrusion detection systems.
