🧰 Requirements

• Cisco Packet Tracer (version 7.2 or later)
• Basic understanding of router interfaces and IP configuration
• Two Cisco 2911 routers in simulation
• Copper cross-over cable for router-to-router connection

---

📡 Network Topology

[Router0] <--- crossover cable ---> [Router1] GigabitEthernet 0/0: 10.0.0.1/8 GigabitEthernet 0/0: 10.0.0.2/8

⚙ Configuration Steps

🔧 Router0

Using CLI:

enable
configure terminal
hostname Router0
interface gigabitEthernet 0/0
ip address 10.0.0.1 255.0.0.0
no shutdown
exit
exit
write memory

This config is saved in: configs/Router0.txt

---

##🔧 Router1

Using CLI:

enable
configure terminal
hostname Router1
interface gigabitEthernet 0/0
ip address 10.0.0.2 255.0.0.0
no shutdown
exit
exit
write memory

This config is saved in: configs/Router1.txt

---

🧪 Testing Connectivity

After configuring both routers, test the connection with a ping command:

ping 10.0.0.1 # From Router0 ping 10.0.0.2 # From Router1

If the ping is successful, the routers are correctly connected and communicating.

See the screenshots in the screenshots/ folder for visual verification.

🧰 Troubleshooting Tips

Issue Possible Cause Solution

No ping response Interfaces are down Ensure no shutdown is used Wrong IP address Misconfigured IP Re-check the CLI commands IP conflict Same IP on both routers Assign unique IPs
