BN202 Internetworking Technologies: Network Design and Plan

This report outlines the design and implementation of a medium-sized network for a telecommunications company with four branches. The design incorporates subnetting to allocate network addresses for varying numbers of customers across different branches (Melbourne, Canberra, Adelaide, and Brisbane) and a headquarters (HQ). Key technologies used include VLANs, DHCP for dynamic IP address allocation, and VTP for VLAN management. The report details hardware and software requirements, provides a network topology diagram, and justifies design choices. Configuration examples are provided for Cisco switches and routers, including VLAN creation, trunk and access interface configuration, sub-interface configuration, and DHCP pool setup. Routing is implemented using RIP, and VTP configuration steps are outlined. Testing procedures, including DHCP IP allocation verification and ping tests between devices, are documented to ensure connectivity. The conclusion summarizes the successful design and implementation of the telecommunications network, with references provided for Cisco IOS configuration and VLAN ACLs. Desklib provides past papers and solved assignments for students.

Project Scope
It is a medium based network. The telecommunication company provides their service to their
customer via four branches. Each branches has different number of customers. We should need to
design the network topology using subnetting concepts for various number of hosts/customers
Project Requirements
It describes four branches of network which is used to implement the VLAN, DHCP and VTP
configuration for customer service. Each customer can communicate with different area of customer
themselves.
Network Design Strategy
We need to implement the subnetting concepts to allocate the network address for different
number of customers. Each network should communicate between themselves dynamically

Network Topology Diagram
Justification
Each branch has four departments. I have implemented the four departments in Canberra
Network. In HQ, I have added three servers which should communicate with other branches also. All
Canberra IP are set from DHCP Server. VTP Server is added in Melbourne network
