            Handwritten notes taken during the year may be taken into the examination.

 

----------

Y2 Practical Router Configuration assessment

Time allowed 2 ½  hours

 

No assistance will be given unless you experience hardware failure.

 

You may use handwritten notes to assist you in this assessment. No printed or photocopied notes will be allowed.

 

Please read the instructions carefully before beginning this assessment.

 

You will work in SILENCE

Instructions

You will take this assessment in TWO parts. For the first hour, you will write your configurations and draw a network diagram on the A3 sheet provided. Be sure to write your name and student number clearly on the paper.

 

When the first hour is complete, you will use the next 80 minutes to apply the configurations that you have written to the routers.

 

Network Diagram

Note that the interface names will differ depending on the router model that you are working on. You MUST issue the command show ip interface brief on each router to check the names of the actual interfaces for that router.

 

 

 

 

 

Network Design – Value 30%

Time allowed 1 Hour

Instructions

You will be given ONE hour to design your network. Please put ALL details on the A3 paper provided.

 

Please refer to the diagram on page 2 when reading the instructions below.

 

You may use the Ciscopedia installed on your PCs or your notes to help you with the required commands.

 

Make sure to include a clear diagram of your network on the A3 paper supplied with all interface and addressing details. You should also write all of your configurations for the routers on the A3 paper.

Subnetting the Network

 

You have been given an address block by your instructor. Please write this address block here.

 

__________________________________________________________________

 

You will use addresses from this block to set up your network.

 

The LAN on R1 requires at least 200 host addresses.

 

Use the lowest address from this block for the Ethernet interface of R1.

 

The LAN on R2 requires at least 200 host addresses.

 

Use the lowest address from this block for the Ethernet interface of R2.

 

The LAN on R3 requires at least 200 host addresses.

 

Use the lowest address from this block for the Ethernet interface of R3.

 

Use /30 addresses from the remaining address space for the serial link between the routers to conserve addresses.

 

Configure a loopback address on R1 using the address 11.0.0.1 /32

 

Configure a loopback address on R2 using the address 12.0.0.1 /32

 

Configure a loopback address on R3 using the address 13.0.0.1 /32

 

 

Router Configuration

 

The host name for R1 should be ‘Chatham’.

 

The host name for R2 should be ‘Rochester’.

 

The host name for R3 should be ‘Strood’.

 

Set up a message of the day for all routers that reads:

 

‘Assessment Network L2’

 

Set up an encrypted enable password of ‘class’

 

Create a login password on TELNET (vty) lines 0 to 4 of ‘cisco’.

 

Give all interfaces that you are using a description as follows:

 

All serial interfaces: ‘WAN link’

 

Ethernet interface on R1: ‘Chatham office LAN’

 

Ethernet interface on R2: ‘Rochester office LAN’

 

Ethernet interface on R3: ‘Strood office LAN’

 

The serial links should have a clock rate of 56000 bps

 

Use point-to-point protocol as the encapsulation over the serial links.

 

Set up an access control list to prevent all addresses on the Ethernet network on R1 from reaching a web server on the Ethernet LAN on R2.

 

Use RIP version 2 as your routing protocol. Be sure to include all network addresses when setting up the routing protocol.

 

Map your host names to the IP addresses of ALL the interface addresses that are attached to each router.

 

Part 2 - Setting up and configuring the network – Value 40%

Time allowed 80 minutes.

 

Log into Netlab (http:// netlab1.gre.ac.uk) and use your standard login to enter the router session that has been created for you.

 

Now you should apply your configurations to your routers.

 

Do not apply your access control lists until you are happy that the network has complete connectivity.

Assessing the network – Value 30%

 

When you have completed the router configuration, your invigilator will need to check that the router setup works correctly.

 

You will be asked to demonstrate the following:

 

 

 

Task to perform

YES

NO

1

Show the routing tables for each of the routers

 

 

 

2

Hosts on Chatham LAN can ping Hosts on Rochester LAN

 

 

 

3

Hosts on Rochester LAN can ping Hosts on Strood LAN

 

 

 

4

Use the cisco discovery protocol the show the platform of the Strood and Chatham routers from Router 2

 

 

5

Use an extended ping to prove that the Chatham router can ping the loopback address on the Rochester router

 

 

6

Show that the Chatham router can ping the Rochester router by host name

 

 

7

Show that the Strood router can ping the Chatham router by host name

 

 

8

Prove using a show command that the DCE end of the WAN link is on the s0/0 interface on Router 1

 

 

9

Use a debug command to show the arrival of RIPv2 updates

 

 

 

10

 

Show that you can open a telnet session into another router
