Objectives
Part 1: Prepare the Topology and Initialize Devices
Part 2: Configure Devices and Verify Connectivity
Part iii: Brandish Device Information
Background / Scenario
This is a comprehensive lab to review previously covered IOS commands. In this lab, you will cable the equipment as shown in the topology diagram. Y'all will so configure the devices to lucifer the addressing table. Afterwards the configurations have been saved, you will verify your configurations past testing for network connectivity.
After the devices take been configured and network connectivity has been verified, you volition employ IOS commands to retrieve information from the devices to answer questions about your network equipment.
This lab provides minimal assistance with the bodily commands necessary to configure the router. Test your cognition past trying to configure the devices without referring to the content or previous activities.
Note: The routers used with CCNA easily-on labs are Cisco 1941 Integrated Services Routers (ISRs) with Cisco IOS Release 15.two(4)M3 (universalk9 image). The switches used are Cisco Catalyst 2960s with Cisco IOS Release 15.0(ii) (lanbasek9 image). Other routers, switches, and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and output produced might vary from what is shown in the labs. Refer to the Router Interface Summary Tabular array at the end of this lab for the correct interface identifiers.
Note: Ensure that the routers and switches have been erased and take no startup configurations. Consult with your instructor for the procedure to initialize and reload a router and switch.
Required Resources
- one Router (Cisco 1941 with Cisco IOS Release 15.2(iv)M3 universal image or comparable)
- one Switch (Cisco 2960 with Cisco IOS Release xv.0(ii) lanbasek9 image or comparable)
- ii PCs (Windows seven or eight with concluding emulation program, such as Tera Term)
- Console cables to configure the Cisco IOS devices via the console ports
- Ethernet cables equally shown in the topology
Note: The Gigabit Ethernet interfaces on Cisco 1941 routers are autosensing and an Ethernet straight-through cablevision may be used between the router and PC-B. If using some other model Cisco router, it may be necessary to use an Ethernet crossover cablevision.
Role 1: Gear up Topology and Initialize Devices
Stride 1: Cable the network as shown in the topology.
- Adhere the devices shown in the topology diagram, and cable, equally necessary.
- Power on all the devices in the topology.
Step ii: Initialize and reload the router and switch.
If configuration files were previously saved on the router and switch, initialize and reload these devices back to their basic configurations.
Office 2: Configure Devices and Verify Connectivity
In Part 2, yous will fix up the network topology and configure bones settings, such equally the interface IP addresses, device access, and passwords. Refer to the Topology and Addressing Table at the start of this lab for device names and address information.
Step 1: Assign static IP information to the PC interfaces.
- Configure the IP accost, subnet mask, and default gateway settings on PC-A.
- Configure the IP address, subnet mask, and default gateway settings on PC-B.
- Ping PC-B from a command prompt window on PC-A.
Why were the pings not successful?
____________________________________________________________________________________
The router interfaces (default gateways) accept non been configured nevertheless then Layer 3 traffic is non existence routed between subnets.
Step 2: Configure the router.
- Console into the router and enable privileged EXEC style.
- Enter configuration mode.
- Assign a device proper name to the router.
- Disable DNS lookup to prevent the router from attempting to translate incorrectly entered commands as though they were host names.
- Assign grade as the privileged EXEC encrypted password.
- Assign cisco every bit the console password and enable login.
- Assign cisco as the VTY password and enable login.
- Encrypt the articulate text passwords.
- Create a banner that warns anyone accessing the device that unauthorized access is prohibited.
- Configure and activate both interfaces on the router.
- Configure an interface clarification for each interface indicating which device is connected to it.
- Save the running configuration to the startup configuration file.
- Set the clock on the router.
Note: Use the question marking (?) to aid with the correct sequence of parameters needed to execute this command. - Ping PC-B from a command prompt window on PC-A.
Were the pings successful? Why?
____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Yes. The router is routing the ping traffic across the ii subnets. The default settings for the 2960 switch will automatically turn up the interfaces that are continued to devices.
Part 3: Brandish Device Data
In Role 3, you will use show commands to recollect information from the router and switch.
Step 1: Retrieve hardware and software data from the network devices.
- Utilise the show version command to reply the following questions about the router.

What interface types are associated to the C coded routes?
_______________________________________________________________________________________
Answers may vary depending of router type, but on the 1941 the correct answer is G0/0 and G0/ane.
Step 3: Display interface data on the router.
Utilise the evidence interface g0/1 to answer the following questions.
R1# show interfaces g0/1
GigabitEthernet0/i is upwards, line protocol is upwardly

What is the operational status of the G0/1 interface?
_______________________________________________________________________________________
GigabitEthernet0/ane is up, line protocol is upward
What is the Media Access Control (MAC) address of the G0/1 interface?
_______________________________________________________________________________________
Answers volition vary only will appear in the grade of: xxxx.xxxx.xxxx, where each x volition be replaced with a hexadecimal number.
How is the Internet address displayed in this control?
_______________________________________________________________________________________
Cyberspace address is 192.168.i.one/24.
Step 4: Display a summary list of the interfaces on the router and switch.
There are several commands that can be used to verify an interface configuration. One of the most useful of these is the bear witness ip interface brief control. The control output displays a summary listing of the interfaces on the device and provides immediate feedback to the condition of each interface.
- Enter the testify ip interface brief command on the router.

Reflection
- If the G0/1 interface showed administratively down, what interface configuration command would you use to plough the interface up?
_______________________________________________________________________________________
R1(config-if)# no shut - What would happen if you had incorrectly configured interface G0/1 on the router with an IP accost of 192.168.1.2?______________________________________________________________________________________________________________________________________________________________________________
PC-A would not be able to ping PC-B. This is because PC-B is on a different network than PC-A which requires the default-gateway router to road these packets. PC-A is configured to utilise the IP address of 192.168.1.ane for the default-gateway router, but this address is non assigned to any device on the LAN. Any packets that need to be sent to the default-gateway for routing will never reach their destination.

| Notation: To find out how the router is configured, wait at the interfaces to place the router type and how many interfaces the router has. There is no way to effectively list all the combinations of configurations for each router course. This tabular array includes identifiers for the possible combinations of Ethernet and Series interfaces in the device. The tabular array does non include any other type of interface, even though a specific router may contain one. An instance of this might exist an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to correspond the interface. | ||||
