The ethernet interface of the router is on the same network as the TFTP server and the procedure is performed via the console and not via telnet, as the routing functions are disabled during the process. Having said that we can proceed to configure the ethernet interface of the router with an IP address:
Router # configure terminal
Router (config) # interface ethernet0
Router (config-if) # ip address 192.168.0.2 255.255.255.0
Router (config-if) # no shutdown
Router (config-if) # exit
Router (config) # exit
Router #
Now make sure the TFTP server is running and launch the old version that will copy the IOS on the TFTP
Router # copy flash tftp
System flash directory:

[OK]
Now we can copy the new IOS version
Router # copy tftp flash **** NOTICE **** Flash load helper v1.0 This process will accept the copy options and then terminate the current system image to use the ROM based image for the copy. Routing functionality will not be available During That Time. If you are logged in via telnet, this connection will terminate. Users with console access can see the results of the copy operation. ---- ******** ---- Proceed?
