In this scenario, a single Layer 2 switch is used to create and manage three VLANs: VLAN 1, VLAN 2, and VLAN 3. Each VLAN is assigned specific ports and clients. The goal is to show how VLANs isolate broadcast domains, ensuring traffic within one VLAN does not interact with other VLANs. This scenario focuses on foundational VLAN segmentation concepts.

This lab involves configuring and troubleshooting IPv6 static routing in a simulated environment. The network consists of two routers (R1 and R2) connected via an Ethernet link, with each router having a directly connected LAN.

A company has implemented ROAS for inter-VLAN routing. However, users are reporting that they cannot communicate between VLANs. The network administrator must troubleshoot the router, switch, and host configurations to resolve the issues.

A company’s IT team is receiving reports that internal devices cannot reach the internet. The administrator must investigate default route settings, check if the default gateway is properly assigned, and test connectivity after fixing the routing issues.

A company is experiencing intermittent OSPF issues where some routers fail to form adjacencies or routes do not propagate correctly. The administrator must identify and fix the misconfigurations preventing stable OSPF operation.

This lab focuses on configuring and verifying Dual-Stack (IPv4 & IPv6) on Routers, allowing IPv4 and IPv6 to operate simultaneously. The network consists of two routers (R1 and R2) and two clients (PC1, PC2), with each device having both an IPv4 and IPv6 address.

Design a real-world SOHO Ethernet LAN from scratch — just like you’d do on your first networking job. This beginner-friendly lab walks you through device setup, IP addressing, and full connectivity verification using

Ever wondered how different departments in a company stay separate — but still talk to each other when needed? In this lab, you’ll build a real-world VLAN setup across two switches and connect them to a router using trunk links and sub-interfaces. It’s where VLANs meet routing — just like in real enterprise networks.

Start here if you’re new to VLANs. In this lab, you’ll create and assign VLANs on a single switch — learning how to segment your network and organize devices like a pro. It’s the foundation for everything VLAN-related.

This lab takes you beyond the basics of static routing. You’ll connect multiple routers and configure logical IP routes between them, simulating how real businesses route traffic across different locations or departments. A great practice before jumping into dynamic routing protocols like OSPF.
