Case Study CCNA3: Switching Basics and Intermediate Routing

Alessandro Pensato
Alessandro Pensatohttp://www.alessandro-pensato.it
Ciao a tutti, sono Alessandro, sono nato a Palermo il 24/01/1983 e vivo a qualche chilometro dalla città. Da anni coltivo la passione per i computer e tutto quello che ci sta attorno, con un occhio di riguardo per il mondo delle reti. Nel 2000 mi avvicino al mondo di Linux e ne resto impressionato da ciò che consente di fare, nonchè alla filosofia dell’opensource. Nel Aprile 2005 ho conseguito la certificazione Cisco CCNA. Da Novembre 2006 sono membro del CUG. Ho completato il corso HP IT Essential I e II e Cisco Network Security. Ho svolto uno stage presso Jump2Future dove mi sono occupato di redigere una ralazione per la realizzazione di un cluster basato su RedHat GFS (Global File System). Lavoro per l’IBIM-CNR di Palermo dal 2002 come tecnico informatico e gestione rete. Sto cominciando ad acquisire conoscenze nel campo del VoIP con software quali Trixbox e Elastix, realizzazione e uso di macchine virtuali basate su VMWare.

Summary of the Company and Network Requirements

The XYZ Research Company is a small company that develops high-speed wireless products. The main office occupies two buildings in Sydney. One building is for the Administration Group. The other building is for the Sales and Marketing Group, and the Research and Development Group. The Research Group and the Sales and Marketing Group will each have employees located on all three floors of the main building. The XYZ Research Company also has a Sales Branch Office located in Melbourne. The company is implementing a wired network that should support 100% growth over the next five to ten years. A logical diagram has been provided.

Our task is to design, implement, and fully document the XYZ Research Company network. In addition to a formal report, we are asked to prepare a prototype of the network built, before it is fully implemented, in order to verify that it will meet the company’s needs.

XYZ Research Company Requirements

  • 18 employees in the Research and Development Group
  • 9 employees in the Sales and Marketing Group
  • 7 employees in the Administration Group
  • 5 employees in the Remote Sales office
  • Lifetime maximum of 5 servers on separate subnet, regardless of company growth.
  • Use subnet 200.200.100.0/30 for connection to Internet router.
  • Use public class C network 223.0.0.0 for internal addressing.
  • Use VLSM for IP addressing.
  • Expect 100% growth of current IP requirements and when determining the size of subnets.
  • All network devices must have IP addresses assigned.
