Objectives

Part 1: Set Up the Topology and Initialize Devices

Part 2: Configure Devices and Verify Connectivity Part 3: Display Router Information

Background / Scenario

This is a comprehensive Packet Tracer Physical Mode (PTPM) activity to review previously covered IOS router commands. In Parts 1 and 2, you will cable the equipment and complete basic configurations and interface settings on the router.

In Part 3, you will use SSH to connect to the router remotely and use the IOS commands to retrieve information from the device to answer questions about the router.

For review purposes, this activity provides the commands necessary for specific router configurations.

Instructions

Part 1: Set Up the Topology and Initialize Devices

Step 1: Cable the network as shown in the topology.

a. Click and drag the Cisco 4321 ISR, the Cisco 2960 Switch, and the Server from the Shelf to the Rack. b. Click and drag the PC from the Shelf to the Table.

3. Cable the devices as specified in the topology diagram. Use Copper Straight-through cables for network connections.
4. From the PC, connect a Console Cable to the Cisco 4321 ISR.
5. Power on the Cisco 4321 ISR, PC-A, and Server. The power button for Server is on the bottom right.

The 2960 switch should power on automatically.  Part 2: Configure Devices and Verify Connectivity

Step 1: Configure the PC interfaces.

1. Configure the IP address, subnet mask, and default gateway settings on PC-A.
2. Configure the IP address, subnet mask, and default gateway settings on Server.

Step 2: Configure the router.

Open configuration window

1. Console into the router and enable privileged EXEC mode.
2. Enter configuration mode.
3. Assign a device name to the router.
4. Set the router’s domain name as ccna-lab.com.
5. Encrypt the plaintext passwords.
6. Configure the system to require a minimum 12-character password.
7. Configure the username SSHadmin with an encrypted password of 55Hadm!n2020.
8. Generate a set of crypto keys with a 1024 bit modulus.
1. Assign $cisco!PRIV* as the privileged EXEC password.
10. Assign $cisco!!CON* as the console password. Configure sessions to disconnect after four minutes of inactivity, and enable login.
11. Assign $cisco!!VTY* as the vty password. Configure the vty lines to accept SSH connections only. Configure sessions to disconnect after four minutes of inactivity, and enable login using the local database.
50. Create a banner that warns anyone accessing the device that unauthorized access is prohibited. m. Enable IPv6 routing.

14. Configure all three interfaces on the router with the IPv4 and IPv6 addressing information from the addressing table above. Configure all three interfaces with descriptions. Activate all three interfaces.

The router should not allow vty logins for two minutes if three failed login attempts occur within 60 seconds.

• Set the clock on the router.
• Save the running configuration to the startup configuration file.

Question:

What would be the result of reloading the router prior to completing the copy running-config startupconfig command? Type your answers here.

Close configuration window

Step 3: Verify network connectivity.

1. Using the command line at PC-A, ping the IPv4 and IPv6 addresses for Server.

Question:

Were the pings successful?

Type your answers here.

2. From PC-A, remotely access R1 using the Telnet / SSH client.

Using the Telnet / SSH client on PC-A, open an SSH session to the R1 Loopback interface IPv4 address. Ensure that the Connection Type is set to SSH and use SSHadmin as the username. When prompted, enter the password 55Hadm!n2020.

Question:

Was remote access successful?

Type your answers here.

3. Using the Telnet / SSH client on PC-A, open an SSH session to the R1 Loopback interface IPv6 address. Ensure that the Connection Type is set to SSH and use SSHadmin as the username. When prompted, enter the password 55Hadm!n2020.

Questions:

Was remote access successful?

Type your answers here.

Why is the Telnet protocol considered to be a security risk?

Type your answers here.

Part 3: Display Router Information

In Part 3, you will use show commands from an SSH session to retrieve information from the router.

Step 1: Establish an SSH session to R1.

Using Telnet / SSH client on PC-A, open an SSH session to the R1 Loopback interface IPv6 address and log in as SSHadmin with the password 55Hadm!n2020.

Step 2: Retrieve important hardware and software information.

1. Use the show version command to answer questions about the router.

Questions:

What is the name of the IOS image that the router is running?

Type your answers here.

How much non-volatile random-access memory (NVRAM) does the router have?

Type your answers here.

How much Flash memory does the router have?

Type your answers here.

2. The show commands often provide multiple screens of outputs. Filtering the output lets you display certain sections of the output. To enable the filtering command, enter a pipe (|) character after a show command, followed by a filtering parameter and a filtering expression. You can match the output to the filtering statement by using the include keyword to display all lines from the output that contain the filtering expression. Filter the show version command, using show version | include register to answer the following question.

Question:

What would be the boot process for the router on the next reload if the configuration register was 0x2142?

Type your answers here.

Step 3: Display the startup configuration.

1. Use the show startup-config command on the router to answer the following question.

Question:

How are passwords presented in the output?

Type your answers here.

2. Use the show running-config | section vty command.

Question:

What is the result of using this command?

Type your answers here.

Step 4: Display the routing table on the router.

Use the show ip route command on the router to answer the following questions.

Questions:

What code is used in the routing table to indicate a directly connected network?

Type your answers here.

How many route entries are coded with a C code in the routing table?

Type your answers here.

Step 5: Display a summary list of the interfaces on the router.

1. Use the show ip interface brief command on the router to answer the following question.

Question:

What command changed the status of the Gigabit Ethernet ports from administratively down to up?

Type your answers here.

2. Use the show ipv6 int brief command to verify IPv6 settings on R1.

Question:

What is the meaning of the [up/up] part of the output?

Type your answers here.

3. On Server, change its configuration so that it no longer has a static IPv6 address. Then, issue the ipconfig command on Server to examine the IPv6 configuration.

Questions:

What is the IPv6 address assigned to Server?

Type your answers here.

What is the default gateway assigned to Server?

Type your answers here.

From PC-B, issue a ping to the R1 default gateway link local address. Was it successful?

Type your answers here.

From Server, issue a ping to the R1 IPv6 unicast address 2001:db8:acad::1. Was it successful?

Type your answers here.
