Develop an IP Addressing Scheme (25 marks)

Assessment Objectives

Part 1: Develop an IP Addressing Scheme (25 marks)

Part 2: Configure Device IP address and Security Settings (47 marks)

Part 3: Test and Verify IPv4 and IPv6 End-to-End Connectivity (28 marks)

Scenario

You are required to build and configure the devices in a small network as shown in the above topology in Packet Tracer. 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 IP addressing scheme file for your allocated IPv4 network address. Use variable-length subnet masking (VLSM) for your design to minimise wastage. You will subnet the provided IPv4 network address to provide IP addresses to the two subnets that will support the required number of hosts. Subnet A has 31 hosts and subnet B has 63 hosts. PC-A is in subnet A and PC-B is in subnet B. 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 (6 marks)

b) Record your subnet assignment in the table below (12 marks)

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

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

Assign the second IPv4 address of the relevant subnet to S1

c) Assign the first IP address of 2001:db8:acad:0001::/64 network to R1’s G0/0/1 interface, second address to S1 and third address to PCA. Assign the first IP address of 2001:db8:acad:0002::/64 network to R1’s G0/0/0 interface and second address to PCB. Record the IPv6 addresses information for each device in the table (7 marks)

 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)

Set description for the interface
Assign IPv4 and IPv6 unicast and link-local addresses

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

Set description for the interface
Assign IPv4 and IPv6 unicast and link-local addresses

Step 2: Verify intermediary devices configuration. (4 marks)

Use the appropriate commands on the intermediary devices to provide evidence for your configuration.  Screenshots should be clearly labelled showing the relevant configuration.

Step 3: Configure host computers. (4 marks)

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

Step 4: Verify host computers configuration (4 marks)

Use the appropriate commands on the host computers to provide evidence for your configuration.  Screenshots 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 screenshot with the result of the ping command for each test should also be provided. (14 marks)

Use the following table to methodically verify connectivity with each network device. Take corrective action to establish connectivity if a test fails:
