Task 1: Configure Cisco Router Global Configuration Settings

Step 1. Physically connect devices. Connect the console or rollover cable to the console port on the R1-ISP and R2-Central .With 2 different computers, one per network. Ensure that power has been applied to the host computer, switch and router.

Step 2. Connect host computer to router through PT Terminal. Start the PT Terminal program by clicking on Host1 | Desktop Tab | Terminal Leave all values at default when you click terminal.

Step 3. Configure global configuration hostname setting. What two commands may be used to leave the privileged exec mode?What shortcut command can be used to enter the privileged exec mode?Examine the different configuration modes that can be entered with the commandconfigure?Write down the list of configuration modes and description. From the privileged exec mode,enter global configuration mode:router# configure terminalrouter(config)#

What three commands may be used to leave the global configuration mode and return to theprivileged exec mode?What shortcut command can be used to enter the global configuration mode?Set the device hostname to R1-ISP :router(config)# hostname R1-ISPR1-ISP(config)#

Do the same with router 2

Step 4. Configure a MOTD banner. The MOTD banner is displayed on all connections before the login prompt. Use theterminating character on a blank line to end the MOTD entry: R1-ISP (config)# banner motd %Enter TEXT message.End with the character '%' *** Unauthorized access is prohibited and

will be prosecuted. *** %R1-ISP (config)#

Task 2: Configure Cisco router password access Access passwords are set for the privileged exec mode and user entry point such asconsole, aux, and virtual lines. The privileged exec mode password is the most criticalpassword, since it controls access to the configuration mode. Step 1: Configure the enable and privileged exec password.

Step 2: Configure the console password.

Set the console access password to cisco. The console password controls console access tothe router. R1-ISP (config)# line console 0R1-ISP (config-line)# password ciscoR1-ISP (config-line)# login


Step 3: Configure the virtual line password.

Set the virtual line access password to cisco. The virtual line password controls Telnetaccess to the router. In early Cisco IOS versions, only five virtual lines could be set, 0through 4. In newer Cisco IOS versions, the number has been expanded. Unless a telnetpassword is set, access on that virtual line is blocked. R1-ISP (config-line)# line vty 0 4R1-ISP (config-line)# password ciscoR1-ISP (config-line)# login R1-ISP (config-line)# exit


Task 3: Configure Cisco Router Interfaces

Step 1: Configure the routers fa0/0 interface with the last usableaddress in the second subnet.

R1-ISP (config)# interface fa0/0R1-ISP (config-if)# description Connection to Host1 with crossovercableR1-ISP (config-if)# ip address address mask R1-ISP (config-if)# no shutdownR1-ISP (config-if)# end R1-ISP #

Do the same for 2 routers and for each interfaces.

Step 3: Configure the host computer.

Configure the host computer for LAN connectivity. Recall that the LAN configuration windowis accessed by clicking the PC going to the Desktop tab and then clicking IP configurations.Fill in the following fields:

Step 4: Verify network connectivity. Use the ping command to verify network connectivity with the router. If ping replies are notsuccessful troubleshoot the connection. You can use ping and tracert command from a pc or a router.

Task 4: Save the Router Configuration File Cisco IOS refers to RAM configuration storage as running-configuration, and NVRAMconfiguration storage as startup-configuration. For configurations to survive rebooting or power restarts, the RAM configuration must be copied into non-volatile RAM (NVRAM). Thisdoes not occur automatically, NVRAM must be manually updated after any changes aremade.

Step 1: Compare router RAM and NVRAM configurations. Use the Cisco IOS show command to view RAM and NVRAM configurations. Write down one possible shortcut command that will display the contents of NVRAM. Displaythe contents of NVRAM. If the output of NVRAM is missing, it is because there is no savedconfiguration.: R1-ISP # show startup-configR1-ISP #show running-config

Step 2: Save RAM configuration to NVRAM. For a configuration to be used the next time the router is powered on or reloaded, it must be

manually saved in NVRAM. Save the RAM configuration to NVRAM: R1-ISP # copy running-config startup-configDestination filename [startup-config]? Building configuration... [OK]R1-ISP #
