BEng Final Year Project: Used Cisco switches and routers to build a network for a company with two geographical sites. In this project, was tasked with identifying the requirements and designing a network architecture based on the 7 OSI Layer model and TCP/IP model for the corporation to share information and resource between two site locations. The following industrial networking protocols were used in designing the network: - Virtual Local Area Network (VLAN) - Hot Standby Router Protocol (HSRP) - Load Balancing with Multi-VLANs HSRP (MHSRP) - VLAN Trunking Protocol (VTP) - Spanning Tree Protocol (STP) - Access Control List (ACL) - Network Address Translation (NAT)
