🔌 Layer 2 Switch vs Layer 3 Switch — What’s the Difference? Understanding the difference between Layer 2 and Layer 3 switches is fundamental for every network engineer. 🔹 Layer 2 Switch • Operates at the Data Link Layer • Uses MAC addresses to forward frames • Supports VLAN segmentation • Access ports connect end devices • Typically operates within a broadcast domain 🔹 Layer 3 Switch • Operates at the Network Layer • Uses IP addresses for routing • Can perform both Layer 2 switching and La...
Layer 2 vs Layer 3 Switch Do you know the difference between Layer 2 and Layer 3 switches? Layer 2 works with MAC addresses and reduces local traffic, while Layer 3 routes data based on IP addresses with multiple broadcast domains. Each plays a vital role in networking efficiency.

Layer 3 Routing Protocols
🌐 Network Protocols by Layer – The Foundation of Modern Networking! 🚀 Every packet you send travels through multiple networking layers, each with its own set of protocols and responsibilities. From HTTP, HTTPS, DNS, and DHCP at the Application Layer to TCP/UDP at the Transport Layer and ICMP, IPsec, MPLS, EIGRP, and BGP at the Network Layer, understanding where each protocol operates is essential for effective troubleshooting and network design. Whether you’re preparing for CCNA, CCNP, or C...
