Key Features: * VLAN Segmentation * Inter-VLAN Routing (Router-on-a-Stick) * OSPF Dynamic Routing * DHCP Configuration * DNS Configuration * Access Control Lists (ACLs) * SSH Remote Management * Port Security * Password Encryption * Network Redundancy and Failover Network Components: * 3 Cisco Routers (Main Office, Backup, Branch) * Core Switch * HR, Finance, IT, Management, and Server Switches * DHCP/DNS Server * Client PCs The network was tested for end-to-end connectivity, automatic IP assignment, DNS name resolution, OSPF neighbor formation, ACL enforcement, SSH access, and backup route failover to ensure reliability and security.
