# Question KF7026 – Module IP Route And Trouble Shooting

## Introduction KF7026 – Module IP Route And Trouble Shooting

Dynamic routing algorithms take a small amount of time for routing tables to become stable following a system switch on or network change.  While this time period may be small, significant network traffic could be lost during periods of convergence.  Furthermore, the actual convergence process for networks can be influenced by router settings such as split horizon (for RIP).  The routing algorithms are well documented and deterministic in nature allowing you to predict behaviour.

In this assignment you will study background theory around route convergence so you can predict behaviour of simple topologies. You will then build some real topologies and observe how convergence occurs and compare your observations with theoretical expectancies.

You are to present your work and observations in a short scientific paper.

### Learning Outcomes

The following learning outcomes are being assessed in this assignment

• KU3 Apply tools to solve complex problems.
• IPS1 Design, conduct, evaluate and report experimental work.
• PVA 1 Able to use and apply RFCs as required.

These learning outcomes are as per the Module Specification.

### Assignment Description

You are required to carry out independent study around the convergence of the RIP algorithm.  You should use high quality peer reviewed literature to support your study. This work will form the foundations of a brief theory section in your scientific paper as well as inform thenature of your experimental work.

You are required to conduct experiments on two topologies. Both topologies Figure 1 and Figure 2 are to use 3 routers. One topology will be looped, the other not.

Figure 1 Three router – linear topology

Figure 1 Three router – looped

You are to design experiments that will allow you to examine the route convergence of the topologies shown in Figure 1 and 2.   You will need to observe routing packets flowing between the routers. For the looped topology in Figure 2 you should observe the behaviour of the routers with Split Horizon switch off and on.

#### The Report

It is recommended that you structure your report using the following headings, which will be used to mark the work

The report should comprise of front heading page that includes your name, date, module title/code and a brief abstract.  This should be followed by the main body of the report that should be no longer than 6 sides.
