This document describes the network implemented for NexaTech. The network is built for a single building with four floors, using VLANs for segmentation and OSPF for dynamic routing. The design provides connectivity between all floors with redundant core router links.

My Second Networking Project | Enterprise Network Design I’ve completed my second hands-on networking project using Cisco Packet Tracer, focusing on building a multi-site enterprise network rather than practicing technologies separately. The project includes Headquarters, Branch Office, Data Center, DMZ, multiple VLANs, wireless networks, redundant Core/Distribution layers, and Cisco ASA firewalls. Key technologies implemented: • VLANs, Trunking & Inter-VLAN Routing • OSPF Dynamic Routing • HSRP Gateway Redundancy & Failover • STP & Port Security • Centralized DHCP & DNS • Web, Mail & FTP Services • Syslog & NTP • HQ-to-Branch Connectivity • DMZ & Firewall Integration The most valuable part was troubleshooting real issues involving DHCP, HSRP, routing, VLANs, firewall policies, and service connectivity, which helped me understand how these technologies work together in a complete network. Continuing my CCNA journey with more advanced networking labs. #CCNA #Cisco #Networking #NetworkEngineering #CiscoPacketTracer #OSPF #HSRP #NetworkSecurity
