Enterprise Multi-VLAN Topology

Simulated and validated a scalable enterprise branch topology featuring departmental VLAN isolation (HR, IT, Admin), redundant core switching, and 802.1Q Router-on-a-Stick inter-VLAN routing. Implemented dynamic DHCP pool allocation, edge perimeter defense using Extended ACLs, and NAT Overload (PAT) to route private subnets (192.168.0.0/16) across a simulated ISP WAN to public endpoints (8.8.8.8).

Enterprise Multi-Zone Branch Network Architecture | Cisco Packet Tracer

Cisco Packet Tracer medium enterprise network topology with an ISP, HQ router, main switch, departmental computers, and a web server

Designed and deployed a complete multi-department branch network topology featuring 802.1Q Router-on-a-Stick inter-VLAN routing, dynamic DHCP addressing, and border security via Extended ACLs. Configured Dynamic NAT Overload (PAT) on the edge router to map internal private subnets (192.168.0.0/16) across a simulated ISP WAN connection to public endpoints (8.8.8.8).
