We know some of the usual TFTP server configurations that can be implemented on the router. The next thing that follows is a few steps and commands for the TFTP server routing setup. Hope this article's summary, can provide some reference for everybody.

TFTP Server routing 1, loading from Flash (Flash):

During the configuration process, we typically configure Flash to load the first location of the Cisco router iOS image, which is not affected by network problems from flash loading, Routers can load the iOS image properly even if they are not properly connected to the TFTP server due to a network failure.

It168#configure terminal

it168 (config) #boot system flash My-router[ctrl-z]

It168#copy Running -config startup-config

When using the Boot system command, we need to enter the boot system command in global configuration mode and the location and image filename where Cisco router iOS needs to be located.

TFTP server routing 2, loading

from a TFTP server after the boot system is defined to load iOS from a TFTP server, the iOS image can be loaded from the TFTP server when the iOS image is failed to load from flash.

It168#configure terminal

it168 (config) #boot system tftp Ios-bak 129.0.0.2[ctrl-z]

It168#copy R Unning-config startup-config

TFTP server routing 3, loading from ROM

if both flash and TFTP fail and the Cisco router iOS image is not properly loaded, We can only load from ROM, the iOS image loaded from ROM can only perform part of IOS commands and functions.

It168#configure terminal

it168 (config) #boot system rom[ctrl-z]

It168#copy running-config Star Tup-config

Tip: When using the boot sysTEM commands must pay attention to the order of the input commands, generally in accordance with the order from Flash, TFTP, ROM and so on, in addition to change all the configuration will be configured to copy to the NVRAM, otherwise when you restart the router, Cisco router iOS These configurations will not be stored in effect.
