Learning Objectives

Upon completion of this lab, you will be able to:

• Cable a network according to the Topology Diagram.
• Erase thestartup configuration and reload a router to the default state.
• Perform basic configuration tasks on a router.
• Configure and activate Ethernet interfaces.
• Test and verify configurations.
• Reflect upon and document the network implementation.

Scenario

In this lab activity, you will create a network that is similar to the one shown in the Topology Diagram. Begin bycabling the network as shown in the Topology Diagram. You will then perform the initial router configurations required for connectivity. Use the IP addresses that are provided in the Topology Diagram to apply an addressing scheme to the network devices. When the network configuration is complete, examine the routing tables to verify that the network is operating properly. This lab is a shorter versionof Lab 1.5.1: Cabling a Network and Basic Router Configuration and assumes you are proficient in basic cabling and configuration file management.



Task 1: Cable the Network.

Cable a network that is similar to the one in the Topology Diagram. The output used in this lab is from 1841 routers. You can use any current router in your lab as long as it has the required interfaces as shown inthe topology. Be sure to use the appropriate type of Ethernet cable to connect from host to switch, switch to router, and host to router. Refer to Lab 1.5.1: Cabling a Network and Basic Router Configuration if you have any trouble connecting the devices. Be sure to connect the serial DCE cable to router R1 and the serial DTE cable to router R2.

Answer the following questions:

What type ofcable is used to connect the Ethernet interface on a host PC to the Ethernet interface on a switch? ____Directo____________________

What type of cable is used to connect the Ethernet interface on a switch to the Ethernet interface on a router? _______________Directo___________

What type of cable is used to connect the Ethernet interface on a router to the Ethernet interface on a host PC?________Cruzado_________________


Task 2: Erase and Reload the Routers.


Step 1: Establish a terminal session to router R1.

Refer to Lab 1.5.1, “Cabling a Network and Basic Router Configuration,” for review of terminal emulation and connecting to a router.


Step 2: Enter privileged EXEC mode.



Router>enable
Router#

Step 3: Clear the configuration.

To clear theconfiguration, issue the erase startup-config command. Press Enter when prompted to [confirm] that you really do want to erase the configuration currently stored in NVRAM.

Router#erase startup-config
Erasing the nvram filesystem will remove all files! Continue? [confirm]
[OK]
Erase of nvram: complete
Router#

Step 4: Reload configuration.

When the prompt returns, issue the...
