Today, let’s talk about something deceptively simple but absolutely mission-critical in enterprise routing — Default Route Propagation. You know, in my CCNP classes, I often start the routing discussions with: “What happens when a router doesn’t know where to send a packet?” And the answer […]

We’re going to unravel one of the most critical topics in networking — Loop Prevention Techniques. If you’ve ever spent hours troubleshooting unstable networks, flapping routes, or broadcast storms, chances are, you’ve come face-to-face with some sort of looping issue. In the classroom or during […]

If you’re diving into routing protocols or just wrapping your head around how your router picks the “best” path, you must understand the concept of Administrative Distance (AD). Think of AD like trust levels among friends. You’ve got friends (routing protocols) like OSPF, EIGRP, RIP, […]

We often configure EIGRP and move on, but do we ever pause and ask — how does EIGRP decide which path is the best? The answer lies in its metric calculation — the “math” behind routing decisions. Trust me, once you understand EIGRP’s metric logic, […]

“Should I use static or dynamic routing here?” — welcome to a real-world networking dilemma. When I started out in the networking field, I leaned heavily on static routes because they were simple and easy to control. But as networks grew more complex, I quickly […]
