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 […]

Today we’re diving deep into a topic that often haunts network engineers during real-world implementations and certifications like CCNP or CCIE — Route Redistribution with Tagging. I still remember a consulting project where a simple redistribution misstep created routing loops and service disruption across multiple […]

One small misstep in BGP advertisement can lead to a network disaster — and yes, it has happened to many top companies (some even made the news!). That’s why today, we’re talking about a life-saving skill: BGP Prefix Filtering. I still remember an incident where […]

Today I’m diving into one of the most fundamental yet often misunderstood topics in BGP – the difference between iBGP and eBGP. Whether you’re prepping for CCNA/CCNP or working on a real enterprise network, understanding these two forms of BGP peering is absolutely essential. I […]

Back in my early networking days, I thought BGP worked like OSPF or EIGRP — throw in some networks, and magic happens. But as I dug deeper, I realized BGP is a policy-based routing protocol, not just metric-based. And at the heart of this policy […]

When I first started working with BGP, I thought it was just about connecting two routers and typing in some IP addresses. But oh boy, did I underestimate it! Real-world BGP is like dealing with diplomatic foreign policies—every move matters, every configuration can make or […]

I still remember when I first explored OSPFv3 in a real-world enterprise setup. It was like learning OSPF all over again, but this time with an IPv6 twist. Many students ask me — “Sir, OSPF toh aata hai, but what’s the real difference in OSPFv3?” […]
