Advanced Network Configuration & Routing Project

This repository contains the complete GNS3 project for a complex network configuration.
The project focuses on the implementation and redistribution of various IP routing protocols, including OSPF, BGP, EIGRP, RIP, and static routing.
It also includes detailed configurations for a Frame Relay WAN and VLANs for network segmentation.

📌 Overview

This project showcases a lab network built in GNS3 with multiple routers and switches.
The files provided include the GNS3 project file and outputs from Cisco IOS devices, such as:

• Running configurations
• IP routing tables
• Traceroutes
• VLAN databases

It serves as a practical, in-depth example of a sophisticated network setup involving multiple routing domains, WAN technologies, and traffic engineering techniques.

🌐 Network Topology Visualization

The complete network topology is defined in the 1.gns3 project file.

The layout consists of:

• A core backbone of routers
• Several access-layer switches
• Multiple Frame Relay switches acting as a WAN cloud

🚀 Key Features

• Advanced Dynamic & Static Routing
  Implementation of OSPF (multi-area), EIGRP (multi-AS), RIP, BGP, and static routing.

• Route Redistribution
  Configuration of mutual redistribution between routing protocols for full reachability.

• Layer 3 Switching
  Router with Switch Module (sharifi/SW2) performing access-layer routing.

• Policy-Based Routing (PBR)
  Route-map on R6 influencing the path of specific traffic, overriding standard routing.

• Router-on-a-Stick
  Sub-interfaces on R4 with dot1Q encapsulation for inter-VLAN routing.

• VLAN Segmentation
  VLANs for security and traffic separation: 7, 18, 26, 43, 47, 62.

• Frame Relay WAN
  Frame Relay cloud with virtual switches (FRSW1, FRSW2, FRSW3) for WAN connectivity.

• Access Control
  Extensive use of ACLs for traffic filtering and network security.

⚡ How to Use

1. Explore Configurations
   Review the text files to understand the network's architecture, routing logic, and ACL policies.

2. Load in GNS3
   Open 1.gns3 in GNS3 to view and simulate the topology.

   ⚠️ You must provide your own Cisco IOS images and configure their paths in GNS3.

3. Learn & Experiment
   Use this project as a study resource for networking certifications or to experiment with advanced designs.
