Multi-Branch Enterprise Campus Network Architecture
Nova Logistics is expanding from a central Headquarters into a secondary Regional Distribution Hub. The network requires high availability, dynamic OSPF routing between sites, departmental VLANs, and strict perimeter ACL security.
Departments & User Breakdown
- HQ Administration (50)
- HQ Engineering (60)
- HQ Datacenter Servers (12)
- Branch Operations (80)
- Branch Guest (40)
Physical Facilities & Sites
- HQ Campus (Dallas)
- Regional Hub (Fort Worth)
Technical Requirements
network
Critical
Campus Topology
Design redundant core routers at HQ connected via leased line point-to-point circuits to the Branch edge router.
routing
Critical
OSPF Dynamic Routing
Implement OSPF Single-Area (Area 0) across the WAN links to advertise internal subnets automatically.
security
Critical
Perimeter ACL Security
Deploy extended ACLs to restrict Guest VLAN access strictly to outbound Internet HTTP/HTTPS and DNS, denying all internal RFC 1918 subnets.
vlan
Critical
VLAN Architecture
Implement structured VLAN IDs across HQ (VLAN 10, 20, 100) and Branch (VLAN 30, 40, 200).
Engineering Constraints
[address_space]
Entire corporate address space must be carved from 10.100.0.0/16.
[redundancy]
Core switch links must use RSTP or EtherChannel to prevent single points of failure.
Tasks & Expected Deliverables
Task 1:
Design Master IP & VLSM Allocation
Deliverable: Full IP plan covering WAN /30 links, HQ subnets, and Branch subnets
Task 2:
Define VLAN & Port Mapping Architecture
Deliverable: VLAN plan and Port Mapping tables for Core and Access switches
Task 3:
Build OSPF Routing & Security Plan
Deliverable: Routing plan table with OSPF metrics and Extended ACL security rules table
Task 4:
Create Complete Network Topology & Documentation
Deliverable: Visual SVG topology diagram and technical design markdown document
