CETM51 – Computer Architectures & Networks Assignment 2 of 2
The following outcomes will be assessed: Knowledge
 An appreciation and configuration of the hardware devices of a network system using standard network models, protocols and media.
Skills
 The ability to assemble, configure and operate a network system and apply security measures to it.
Important Information
You are required to submit your work within the bounds of the University Infringement of Assessment Regulations (see your Programme Guide). Plagiarism, paraphrasing and downloading large amounts of information from external sources, will not be tolerated and will be dealt with severely. Although you should make full use of any source material, which would normally be an occasional sentence and/or paragraph (referenced) followed by your own critical analysis/evaluation. You will receive no marks for work that is not your own. Your work may be subject to checks for originality which can include use of an electronic plagiarism detection service.
Where you are asked to submit an individual piece of work, the work must be entirely your own. The safety of your assessments is your responsibility. You must not permit another student to access your work.
Where referencing is required, unless otherwise stated, the Harvard referencing system must be used (see your Programme Guide).
Please ensure that you retain a duplicate of your assignment. We are required to send samples of student work to the external examiners for moderation purposes. It will also safeguard in the unlikely event of your work going astray.

CETM51 Network Implementation Assignment
Instructions:
In teams of no more than four students (one network domain each) you are required to build and test the following network. Part A is to be done in your own time prior to your implementation session. Part B is to be done in a practical session – as defined by your tutor.
The ISP router at the centre of the network shown above has already been configured. All that is needed is the correct serial line connection to your local router. ALL serial interfaces that are under your administrative control and are connected to the ISP should be set up as “DTE” enabled interfaces. All network domains must use the OSPFv2 or OSPFv3 routing protocol in network area 0.
The diagram for this assignment can be found in the accompanying file on your Canvas site for CETM51 – CETM51Assignment2Diagram.pdf
Your Part A section must very clearly indicate which network domain you have selected, and should also show which other group members have taken the other domains.
Part A – Individual Submission:
1. Create an IPv4 scheme using VLSM to cater for the whole network shown – use a separate private address range for each area. You must show ALL working out! You are to ensure that IP address wastage is kept to an absolute minimum.
[25 Marks]
2. Apply the IPv4 addressing scheme to a copy of the diagram.
[5 Marks]
3. Create an IPv6 scheme that could be used in place of the IPv4 scheme. Use appropriate
address types with brief reasoning as to why you make your choices. 4. Apply the IPv6 addressing scheme to another copy of the diagram.
[20 Marks] [5 Marks]

Part B – Practical Simulation:
Build the network you have been given in the diagram on Packet Tracer. The configuration for the ISP router has been provided for you below.
1. Basic Network Configuration: Build your network as shown on your network diagram. This part of the configuration should include all hostnames, interfaces and their IP addressing and OSPF dynamic routing protocol and any necessary static or default routes to get your network areas to communicate (you should only be able to ping border addresses at this point) – ensure these are redistributed.
[15 Marks]
2. Network Enhancements: Configure NAT and PAT on all the border routers and employ Static NAT for the WWW server.
[10 Marks]
3. Network Security Tasks: Given the GRE tunnel map you are provided with, set this up and add it to your routing protocol configuration – OSPF should also authenticate itself with the appropriate pre-shared key – use banana for this. Add an IPSec point-to-point VPN between two of the network areas. It is up to you which you choose.
[20 Marks]
Configuration for ISP Router:
Use a 2811 router and install 4 WIC-1T serial ports in the four vacant slots before configuring it with:
enable
configure terminal
hostname ISP
interface s0/0/0
ip address 1.0.0.1 255.255.255.240 clock rate 64000
no shutdown
interface s0/1/0
ip address 2.0.0.1 255.255.255.240 clock rate 64000
no shutdown
interface s0/2/0
ip address 3.0.0.1 255.255.255.240 clock rate 64000
no shutdown
interface s0/3/0
ip address 4.0.0.1 255.255.255.240 clock rate 64000
no shutdown
exit
ip route 1.0.0.0 255.0.0.0 s0/0/0 ip route 2.0.0.0 255.0.0.0 s0/1/0 ip route 3.0.0.0 255.0.0.0 s0/2/0 ip route 4.0.0.0 255.0.0.0 s0/3/0 exit
