Lab 3 - VLAN Configuration | Creating VLANs & Isolating Broadcast Domains (Cisco Packet Tracer)

In this lab, I demonstrate how to create VLANs and assign switch ports to separate broadcast domains using Cisco Packet Tracer. This is a core Layer 2 concept and a critical building block for CCNA-level networking and real-world enterprise networks. 🔧 Lab Objectives Create multiple VLANs on both access switches: VLAN 10 – Sales VLAN 20 – HR VLAN 30 – IT VLAN 99 – Management Configure access ports and assign them to the correct VLANs: Access-SW1 PC1 (Fa0/2) → VLAN 10 PC2 (Fa0/3) → VLAN 20 Access-SW2 PC3 (Fa0/2) → VLAN 10 PC4 (Fa0/3) → VLAN 30 Ensure all ports are configured in access mode and placed in their intended VLANs 🔍 Key Concept Explained At this stage, devices in the same or different VLANs cannot communicate. This video explains why VLANs create separate broadcast domains, how switches forward frames based on VLAN membership, and why inter-VLAN routing is required to enable communication between VLANs. 🧠 What You’ll Learn How VLANs logically segment a network Why broadcast isolation improves security and performance How access ports differ from trunk ports Why Layer 2 switches alone cannot route between VLANs 📌 Next Lab: Trunking and Inter-VLAN Routing #CCNA #VLAN #Cisco #NetworkingFundamentals #PacketTracer #BroadcastDomains #Switching
