# 🖧 Cisco Packet Tracer Network Simulation Project

## Overview

This project contains a Cisco Packet Tracer simulation showcasing a multi‑segment network topology with dynamic routing, VLAN management, high availability, and core network services.

## Designed Network

## Features & Technologies

The following configurations have been implemented in the network topology:

- **Routing Protocols**: RIP, OSPF, EIGRP

- **Switching Technologies**: EtherChannel, HSRP

- **Access Control**: VLAN configurations, SSH access

- **IP Addressing**: Static and dynamic IP addressing (DHCP)

- **Bandwidth and Delay**: Adjusted for different network scenarios

- **Network Services**: DNS, Web, Email, and Smart Phone configurations

## Implementation Summary

### Key configuration areas include:

1. **Device Initialization**:

    - Assigning IP addresses to routers, switches and PCs

    - Setting up VLANs for segmented network traffic

2. **Protocol Configuration**:

    - Configuring RIP, OSPF, and EIGRP for dynamic routing

    - Redistribution between protocols

    - Implementing EtherChannel for link aggregation

3. **Access and Security**:

    - Setting up SSH for secure remote access

    - Configuring HSRP for high availability

    - ACL to restrict printer access

    - Security hardening with black‑hole VLANs

4. **Network Services**:

    - DNS and DHCP configuration

    - Web and email server setups

    - NAT on wireless routers to support private clients

5. **Performance Tuning**:

    - Adjusting bandwidth and delay settings for different network segments

## How to Use

Install [Cisco Packet Tracer](https://www.netacad.com/courses/packet-tracer) and then simply open the [netlab_project.pkt](netlab_project.pkt). The whole network is in working condition. You can check it by sending a packet from one system to another or through using the PING command in the Cisco Packet Tracer.
