![Route Maps vs Prefix Lists – A Deep Dive for Real-World Networking [ CCNP ENTERPRISE ]_networkjourney](https://networkjourney.com/wp-content/uploads/2025/06/Route-Maps-vs-Prefix-Lists-–-A-Deep-Dive-for-Real-World-Networking-CCNP-ENTERPRISE-.png)
If you’ve ever sat there staring at your router’s CLI wondering whether to use a route map or a prefix list, you’re not alone. I’ve seen many students — even working professionals — struggle with this subtle yet powerful decision. Today, I’ll walk you through […]

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 […]
![Route Redistribution with Tagging – Mastering Controlled Routing Across Protocols [ CCNP ENTERPRISE ]_networkjourney](https://networkjourney.com/wp-content/uploads/2025/06/Route-Redistribution-with-Tagging-–-Mastering-Controlled-Routing-Across-Protocols-CCNP-ENTERPRISE-.png)
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 […]
