![iBGP vs eBGP Differences – A Deep Dive with Real-World Examples [ CCNP ENTERPRISE ]_networkjourney](https://networkjourney.com/wp-content/uploads/2025/06/iBGP-vs-eBGP-Differences-–-A-Deep-Dive-with-Real-World-Examples.png)
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?” […]

In today’s networks, where IPv6 adoption is growing rapidly, you’ll need this skill not just for interviews and certifications but in real-world deployments too. This post will take you step-by-step through: Let’s make EIGRP for IPv6 your comfort zone. Theory in Brief – What is […]

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 […]

If you’re someone preparing for your CCNP or trying to optimize a real-world network, you’ve probably heard about UplinkFast and BackboneFast—two hidden gems in the Spanning Tree Protocol (STP) world. I’ve seen many networks struggle with convergence times due to unnecessary delays, and that’s exactly […]

I want to walk you through something that may seem subtle at first glance—but is absolutely critical when building reliable, loop-free Layer 2 networks: STP tuning. Whether you’re preparing for a CCNP certification, managing a growing enterprise network, or simply refining your EVE-NG lab skills, […]

Today I want to make your STP game stronger with a concept that often confuses even seasoned engineers: Multiple Spanning Tree (MST) Region Configuration. If you’ve worked with classic STP or even Rapid-PVST, you know how tricky it gets as your network grows. MST brings […]
