How to Fix a Routing Loop in CCNA: A Step-by-Step Troubleshooting Guide

Tired of watching your packets bounce endlessly between routers with no destination? Routing loops are a common headache in CCNA networking, especially when working with dynamic protocols like RIP or EIGRP. If left unchecked, they can crash your network, slow traffic, and lead to major configuration nightmares. But the good news? You can fix them with the right knowledge and a bit of practice. In this guide, you'll learn exactly how to fix a routing loop in CCNA using proven methods, tools, and troubleshooting techniques. Understanding Routing Loops the Simple Way A routing loop happens when routers forward data packets in a continuous circle because of faulty or outdated routing information. This happens when each router believes the other has the best path. In CCNA-level networks, understanding routing loops is crucial because they cause network congestion, delays, and packet loss, affecting overall performance and reliability.
