Case Study – Instructor Notes
Phase 1: Project Description
This phase of the case study can begin early in the semester, as students should be familiar
with subnetting.
The entire case study should be discussed in class so that all students understand that the
purpose of this study is not only to practice configuration and troubleshooting, but also to learn
how to document their work. The following are some good web sites that will help the
students' understanding of documentation:

The network address assigned should be one of the private IP address ranges or a subnet of
one:
Class
A
B
C
The routing protocol should be IGRP. The first part of Phase 1 should probably be completed
as a class so that students understand the purpose of the case study. Along with a discussion
of Phase 1, the deliverable piece should also be covered. The instructor should decide
whether or not this is a group project. Certainly each student should be capable of deciding on
IP addresses of interfaces after the IP scheme has been chosen.
The Network Diagram - IP Addressing on page 4 is the first document that should be approved
by the instructor.
Phase 2: IP Addressing
This Phase of the case study should be due after module 4 or 5 is completed.
Students should recreate the drawing during this Phase using CDN, Visio, or a paint program.
In the drawing the students should be advised to insert the appropriate interface connections
on the routers. The drawing should be approved by the instructor.
The following topics can be used for class discussion:
•
The reasons for using private IP addressing
