This document describes the network configuration of multiple switches and routers. Switch 1 (SW1) and Switch 2 (SW2) connect to a core router via trunk ports and contain VLANs for different departments. Switch 3 (SW3) connects to a branch router and also contains VLANs. Switch 4 (SW4) contains both public and private VLANs that connect via trunk ports. A firewall connects externally to the core router and contains multiple IP subnets and VLANs to segregate internal and external traffic.
