Task 2 Assessment Brief

Build and Configure Small Network

Topology

Assessment Objectives

Part 1: Develop an IP Addressing Scheme (30 marks)

Part 2: Configure Device IP address and Security Settings (45 marks)

Part 3: Test and Verify IPv4 and IPv6 End-to-End Connectivity (25 marks)

Scenario

You are required to build and configure the devices in a small network as shown in the above topology. You

must configure a router, switch and PCs to support both IPv4 and IPv6 connectivity. You will configure

security, including SSH, on the router. In addition, you will test and document the network using common CLI

commands.

Requirements

Part 1: Develop an IP Addressing Scheme

a. Please refer to Moodle for your allocated IPv4 address and host requirements for subnet A and

subnet B. You will subnet it to provide IP addresses to the two subnets that will support the required

number of hosts. No subnet calculators may be used. All workout must be shown (without in-depth

discussion on the subnetting method, there will be no mark awarded to this task). Results should

be recorded in the IP Addressing table below (20 marks)

b. Record your subnet assignment in the table below

1) Assign the first IPv4 address of the relevant subnet to each router interface

2) Assign the last IPv4 address of the relevant subnet to each PC NIC

3) Assign the second IPv4 address of the relevant subnet to S1

S1 blank blank blank

PC-B blank blank blank

c. Please refer to Moodle for your allocated IPv6 address. Use the allocated address to create two

subnets for use in this network. Record the IPv6 addresses in the table (10 marks)

d. Record the IPv6 address information for each device

Note: Use FE80::1 as the link-local address on both router interfaces.

Part 2: Configure Device IP Address and Security Settings

Note: Marks will only be awarded if a screenshot evidence of the configuration is provided

Step 1: Configure intermediary devices (35 marks)

? Set the router hostname as R1 (1 mark)

? Set switch hostname as S1 (1 mark)

? Set an encrypted privileges EXEC password for all intermediary devices: ccnaenpass (2 marks)

? Secure the console access to all intermediary devices with the password: ccnaconpass (2 marks)

? Set the minimum length for passwords to be 10 characters (4 marks)

? Create an administrative user in the local database and set the username and password as: (4 marks)

Username: admin

Password: admin1pass

? Configure an MOTD banner for all intermediary devices with the message: No Unauthorised Access! (1

mark)

? Encrypt all the used passwords on all intermediary devices. (2 marks)

? Disable IP domain lookup on all intermediary devices. (2 marks)

? Enable synchronous logging on all intermediary devices to avoid interruptions during configuration tasks.

(4 marks)

? Configure router’s interfaces (6 marks)

o Set description for the interface

o Assign IPv4 and IPv6 unicast and link-local addresses

? Configure switch’s management (SVI) interface (6 marks)

o Set description for the interface

o Assign IPv4 and IPv6 unicast and link-local addresses

Step 2: Verify intermediary devices configuration.

Use the appropriate commands on the intermediary devices to provide evidence for your configuration. Screen

shots should be clearly labelled showing the relevant configuration.

Step 3: Configure host computers. (10 marks)

Configure host computers with IPv4 and IPv6 addresses from their relevant subnets.

Step 4: Verify host computers configuration

Use the appropriate commands on the host computers to provide evidence for your configuration. Screen shots

should be clearly labelled showing the relevant configuration.

Part 3: Test and Verify End-to-End Connectivity

Step 1: Use the ping command to test IPv4 and IPv6 connectivity between all network devices. A clearly

labelled screen shot with the result of the ping command should also be provided. (10 marks)

Use the following table to methodically verify connectivity with each network device. Take corrective action to

establish connectivity if a test fails:

Question:

Step 2: Enter the appropriate CLI command needed to display the following on R1. A copy of the

output of the command on R1 should also be included (15 marks)
