Network Design, Topology, and IP Addressing for Victoria University

This assignment presents a comprehensive network design for a company, encompassing network topology, IP addressing, and routing configurations. The solution begins with a detailed network topology diagram, illustrating the connection from the ISP to redundant routers and departmental networks. It includes a breakdown of IP subnet classification, detailing allocated subnets, masks, network addresses, default gateways, valid host ranges, and broadcast addresses for various departments such as Sport, Health, Business, Engineering, and Human Resources, along with ISP and gateway configurations. The document then provides a labeled network topology diagram specifying network addresses and subnets used by different interfaces. It further elaborates on routing and switching configurations, including the configuration of redundant routers (R0 and R1), switches, and gateway routers, along with the implementation of HSRP for redundancy and RIP for routing. The solution also includes static NAT translation in the gateway router and concludes with references to relevant research papers.

1. Network Topology Design
Figure 1: Design of Network Topology of the Company
The above diagram shows how the company obtains internet access from the ISP
through the gateway router and distributes the connection to two redundant routers in other
buildings. This connection is setup over a Wide Area Network (WAN). The redundant
routers then route the connection to respective departments in the same building.
