VLAN Labs

Segmenting networks isn’t just about organization—it’s about performance, security, and scalability. These VLAN labs demonstrate my ability to design and implement logical network segmentation using Virtual LANs. From assigning ports to specific VLANs to configuring trunk links and enabling inter-VLAN routing, each lab replicates real-world scenarios that improve traffic management and isolate network domains. They reflect my hands-on experience in creating efficient, secure, and structured network topologies essential for modern enterprise environments.

Multi-VLAN Segmentation with Inter-VLAN Routing

VLAN

Simulated a multi-department office network by segmenting devices into VLANs, assigning subnets, and configuring router ports for inter-VLAN routing to enable cross-department communication.

Skills Demonstrated:

Creating and assigning VLANs for department-based segmentation
Calculating and applying subnetting for scalable IP allocation
Configuring access ports for VLAN membership on a switch
Using straight-through cabling to connect endpoint devices
Implementing inter-VLAN routing using separate router interfaces per VLAN
Assigning gateway IP addresses based on subnet design
Verifying VLAN-to-VLAN communication using ping tests
Using CLI commands for hostname config, password hardening, and interface setup
Interpreting router and switch output to validate configuration

Multi-VLAN Segmentation with Trunking and ROAS

VLAN

Designed a multi-VLAN network using two switches and a router, configured trunk ports and VLANs across switches, and implemented Router on a Stick (ROAS) to enable inter-VLAN communication across departments.

Skills Demonstrated:

Creating and assigning VLANs for department-based segmentation
Calculating and applying subnetting for scalable IP allocation
Creating and configuring trunk ports between switches and to the router for VLAN propagation
Naming and managing VLANs using best practices
Simulating a multi-department structure: Sales (VLAN10), HR (VLAN20), Engineering (VLAN30)
Implementing Router on a Stick (ROAS) with subinterfaces using encapsulation dot1q
Setting native VLAN to VLAN1001 for trunk security
Verifying trunk status, VLAN propagation, and ROAS functionality via ping tests
Demonstrating inter-VLAN connectivity with ping replies across VLANs on different switches

Multi-VLAN Segmentation with Layer 3 Switch
