RIP Routing & Subnet Communication Simulation 🚀

This project demonstrates a RIP-based routing setup in a multi-subnet environment using Cisco Packet Tracer. The network topology consists of multiple routers, switches and PCs configured across different subnets, where RIP is used to enable dynamic routing and inter-subnet communication.

Course: Computer Networks (4th Semester)
Tool Used: Cisco Packet Tracer
Focus: Routing Information Protocol (RIP), subnetting, routing table behavior, and connectivity testing.

🧪 What’s Demonstrated

✅ Connectivity Tests

• Successful pings:
  • PC1 ➝ PC2
  • PC1 ➝ PC3
  • PC1 ➝ PC4

🗺️ Routing Table Output

• rip route print output on Router 3, showing dynamically learned routes.

🔎 Traceroute Results

📘 Key Learning

• How routers determine the destination subnet using the network address and subnet mask.
• The role of RIP in learning and distributing routes across a network.
• Verifying communication through ICMP (Ping) and traceroute.
• Understanding how routing tables direct traffic between subnets.

🧠 How Routing Decision Works (Short Answer)

A router determines whether a destination IP is in a particular subnet by performing a bitwise AND operation between the destination IP address and the subnet mask. If the result matches one of its known network addresses (based on its routing table), the router forwards the packet accordingly; otherwise, it looks for a default or next-best route.

📥 How to Run

1. Download or clone this repository:

   git clone https://github.com/Sameed-333/rip-routing-subnet-simulation.git

2. Open RIP-Routing-Simulation.pkt using Cisco Packet Tracer.
3. Use the terminal on PCs to:

• ping other hosts to test connectivity
• tracert to observe hop paths

4. Verify routing tables on routers, and traceroute results from PCs.
