This project simulates the redesign of a flat small business network into a segmented, VLAN-based architecture with inter-VLAN routing using a router-on-a-stick design.
- Separate departments into unique VLANs
- Use a router to enable inter-VLAN communication
- Assign static IPs to all end devices
- Validate successful communication between VLANs
