Ever been in a situation where a static route pointed to a next-hop that silently disappeared, and your router kept blindly forwarding traffic into a black hole? I’ve seen this happen way too often in production networks! That’s where Next-Hop Reachability Tracking saves the day. […]

Can I send traffic based on user type or maybe only during a specific time?” That’s when Conditional Routing enters the game — it’s like having a smart traffic police that directs cars based on who is driving and what the current road conditions are. […]

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, […]

Today I’m going to deep-dive into a very important yet often overlooked concept – the Routing Table Lookup Process. Many of my students know how to configure OSPF, BGP, or EIGRP, but when asked “How does a router actually choose the best route when multiple […]

Ever found yourself in a situation where you wanted to override the default routing decisions of your router? Maybe route specific traffic over a particular WAN link? That’s where Policy-Based Routing (PBR) becomes your best friend. In my experience training hundreds of engineers, I’ve seen […]

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, […]
