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.
