Press Enter when prompted to [confirm] that you really do want to reload the router. After the router

finishes the boot process, choose not to use the AutoInstall facility, as shown:


Would you like to enter the initial configuration dialog? [yes/no]: no

Would you like to terminate autoinstall? [yes]: [Press Return]

Press Enter to accept default.

Press RETURN to get started!



Step 5: Repeat Steps 1 through 4 on router R2 to remove any startup configuration file that may
be present.

Task 3: Perform Basic Configuration of Router R1.

Step 1: Establish a HyperTerminal session to router R1.

Step 2: Enter privileged EXEC mode.

Router>enable

Router#

Step 3: Enter global configuration mode.

Router#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#



Step 4: Configure the router name as R1.

Enter the command hostname R1 at the prompt.

Router(config)#hostname R1

R1(config)#



Step 5: Disable DNS lookup.

Disable DNS lookup with the no ip domain-lookup command.

R1(config)#no ip domain-lookup

R1(config)#


Why would you want to disable DNS lookup in a lab environment?

What would happen if you disabled DNS lookup in a production environment?

Step 6: Configure the EXEC mode password.

Configure the EXEC mode password using the enable secret password command. Use class for

the password.

R1(config)#enable secret class

R1(config)#


Why is it not necessary to use the enable password password command?

Step 7: Configure a message-of-the-day banner.

Configure a message-of-the-day banner using the banner motd command.

R1(config)#banner motd &

Enter TEXT message. End with the character '&'.

********************************

!!!AUTHORIZED ACCESS ONLY!!!

********************************

&

R1(config)#



When does this banner display?

_______________________________________________________________________________

Why should every router have a message-of-the-day banner?

_______________________________________________________________________________

Step 8: Configure the console password on the router.

Use cisco as the password. When you are finished, exit from line configuration mode.

R1(config)#line console 0

R1(config-line)#password cisco

R1(config-line)#login

R1(config-line)#exit

R1(config)#



Step 9: Configure the password for the virtual terminal lines.

Use cisco as the password. When you are finished, exit from line configuration mode.

R1(config)#line vty 0 4

R1(config-line)#password cisco

R1(config-line)#login

R1(config-line)#exit

R1(config)#



Step 10: Configure the FastEthernet0/0 interface.

Configure the FastEthernet0/0 interface with the IP address 192.168.1.1/24.

R1(config)#interface fastethernet 0/0

R1(config-if)#ip address 192.168.1.1 255.255.255.0

R1(config-if)#no shutdown

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed

state to up

R1(config-if)#



Step 11: Configure the Serial0/0/0 interface.

Configure the Serial0/0/0 interface with the IP address 192.168.2.1/24. Set the clock rate to 64000.

Note: The purpose of the clock rate command is explained in Chapter 2: Static Routes.

R1(config-if)#interface serial 0/0/0

R1(config-if)#ip address 192.168.2.1 255.255.255.0

R1(config-if)#clock rate 64000

R1(config-if)#no shutdown

R1(config-if)#



Note: The interface will not be activated until the serial interface on R2 is configured and activated

Step 12: Return to privileged EXEC mode.

Use the end command to return to privileged EXEC mode.

R1(config-if)#end

R1#

Step 13: Save the R1 configuration.

Save the R1 configuration using the copy running-config startup-config command.

R1#copy running-config startup-config

Building configuration...

[OK]

R1#

Task 4: Perform Basic Configuration of Router R2.

Step 1: For R2, repeat Steps 1 through 9 from Task 3.

Step 2: Configure the Serial 0/0/0 interface.

Configure the Serial 0/0/0 interface with the IP address 192.168.2.2/24.

R2(config)#interface serial 0/0/0

R2(config-if)#ip address 192.168.2.2 255.255.255.0

R2(config-if)#no shutdown



%LINK-5-CHANGED: Interface Serial0/0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0/0, changed state

to up

R2(config-if)#
