“CCNA Day 02 | Routers vs L3 Switches vs NGFW | Spine‑Leaf vs 3‑Tier | SOHO, Campus LAN & SD‑WAN”

In this episode, we dive deep into the core building blocks of modern networks — exploring how routers, Layer 3 switches, and next‑generation firewalls (NGFW) shape secure and efficient connectivity.

You’ll learn:

🔹 Router vs. L3 Switch vs. NGFW — functional differences, use‑cases, and performance trade‑offs

🔹 Network Topologies — comparing Spine‑Leaf (the data‑center standard) with the Traditional 3‑Tier design

🔹 Network Types — an overview of SOHO, Campus LAN, and SD‑WAN architectures

Whether you’re a network engineer, architect, or IT student, this session builds the foundation for understanding how enterprise networks are designed, scaled, and secured.

📘 Watch till the end for real‑world design insights and visual breakdowns that make complex architectures easy to grasp.
