The document outlines the steps to implement EIGRP with MD5 authentication using GNS3, including configuring three routers in a ring topology. It details IP address assignments, commands to apply EIGRP and MD5, and concludes with successful implementation. Debugging EIGRP packets is also suggested as part of the process.

Implementing EIGRP with MD5 authentication using GNS3
-- Ankur Soni

2. Step 1.
Connect 3 Router c3700 with fast-ethernet in Ring Topology.

3. Step 2. Start the routers by clicking the start button.
Step 3. Configure R1 as 192.168.1.1 (f0/0) and 192.168.25.1 (f0/1)

4. Step 4.
Configure R2 192.168.1.2 (F0/0) AND 192.168.10.1 (F0/1)

5. Step 5.
Configure R3 as 192.168.25.2 (f0/0) and 192.168.10.2 (f0/1)

6. Step 6. Ping at R3.

7. Step 7. Apply EIGRP at each Router.

9. Step 8. Apply MD5 Authentication.

12. Step 9. Debug EIGRP packets.

13. RESULT
• We have successfully implemented EIGRP with MD5 authentication.
