Enterprise Campus Network - Hierarchical Design
About This Architecture
Enterprise campus network using a three-tier hierarchical design with Palo Alto firewall, H3C S6520 core switches in HA stack, and dual aggregation layers supporting DMZ and internal VLANs. Traffic flows from ISP through the Palo Alto firewall (Untrust/DMZ/Trust zones) to redundant core switches, then to aggregation switches managing VLAN 10, 20, 30, 40, with access switches connecting office PCs, wireless APs, and servers. This architecture delivers carrier-grade availability, network segmentation, and scalability for large enterprise campuses. Fork and customize this diagram on Diagrams.so to match your VLAN scheme, switch models, or add additional security zones.
People also ask
How do I design a hierarchical enterprise campus network with high availability and VLAN segmentation?
This diagram shows a three-tier design: Palo Alto firewall (Untrust/DMZ/Trust) connects ISP to redundant H3C S6520 core switches in HA stack, which feed dual aggregation switches managing VLANs 10-40, then access switches connect office PCs, wireless APs, and DMZ servers. This pattern ensures fault tolerance, network segmentation, and scalability.
