Lab 3: Upgrading the IOS and Restoring a Configuration from TFTP Server ”Part I

Practical Scenario

Sometimes, in the field, you must perform an Cisco IOS Software upgrade, but you do not have local access to the router. You can still perform the upgrade by making an adjacent Cisco router a TFTP server.

Lab Exercise

In this practical exercise, you upgrade one router's IOS from another router's Flash memory. A second part of this exercise consists of copying configs to and from a TFTP server.

Lab Objectives

• Refer to Figure 1-16, and configure the network as shown ”do not configure the loopback address at this time.

  Figure 1-16. Lab 3: Physical Layout and IP Address Map

• To prevent future "crashes" of the Cisco IOS Software on the router rosewell, copy the new Cisco IOS Software from the router ufo to the router rosewell.

• Using TFTP, TFTP the startup-config from router ufo to the TFTP server 172.16.16.254. Edit the configuration with Wordpad, and change the host name to w-balloon. TFTP the configuration back to the router's startup-config. Reload the router.

Equipment Needed

• Two Cisco routers and one Ethernet hub

• One workstation with terminal-emulation software, TFTP software, and TCP/IP configured per Figure 1-16

Physical Layout and Prestaging

TCP/IP must also be configured on this workstation per Figure 1-16.
