Routing and Switching Lesson 1

Welcome back to the channel! In this tutorial, we dive into the core fundamentals of network segmentation by configuring a trunk link between two switches and routing traffic for VLAN 20 and VLAN 40. Whether you're studying for your networking exams or building your homelab, understanding how VLAN tags traverse trunk ports is an essential skill for any aspiring system or network administrator. Watch step-by-step as we set up switch interfaces, verify trunking status, and test connectivity between PCs across different VLANs. 📌 What You’ll Learn in This Video: VLAN Assignment: How to configure access ports and assign PCs to VLAN 20 (Marketing/Sales) and VLAN 40 (IT/Engineering). Trunking Configuration: Setting up IEEE 802.1Q trunk ports to carry multiple VLANs across a single physical link between switches. Verification & Testing: Using essential commands (show vlan brief, show interfaces trunk) to confirm port states. Connectivity Checks: Running ping tests to verify intra-VLAN and inter-VLAN behavior. 🔗 Helpful Resources & Commands Used: vlan 20 / name VLAN20 switchport mode access / switchport access vlan 20 switchport mode trunk / switchport trunk encapsulation dot1q show interfaces trunk 💬 Connect With the Channel: If this video helped you clear up your networking doubts, make sure to Like, Comment, and Subscribe for more tutorials on systems and network administration!
