If any of the above Memory Requirements are Once you have set the variables you can continue on to objective 3 by executing the tftpdnld command with the -r switch to copy the Cisco IOS image from a TFTP Server and load it into ram directly. You do not need a default gateway if your TFTP Server is on the same subnet as the Cisco router youвЂ™re recovering. Shown below is the required variables to execute tftpdnld successfully. You can issue the set command to view the current set variables. r: do not write flash, load to DRAM only and launch imageДЄs per the objectives, weвЂ™re required to set the required variables to execute the tftpdnld command. TFTP_TIMEOUT: Overall timeout of operation in seconds (default=7200) TFTP_RETRY_COUNT: Retry count for ARP and TFTP (default=12) TFTP_SERVER: The IP address of the server to fetch from IP_SUBNET_MASK: The subnet mask for this unitДEFAULT_GATEWAY: The default gateway for this unit The following variables are REQUIRED to be set for tftpdnld: 'ctrl-c' or 'break' stops the transfer before flash erase begins. (Syntax: 'VARIABLE_NAME=value' and use 'set' to show current variables.) Monitor variables are used to set up parameters for the transfer. Use this command for disaster recovery only to recover an image via TFTP. Missing or illegal ip address for variable IP_ADDRESS By executing the tftpdnld you can view all required variables for the command to operate properly This command will copy an IOS image from a TFTP Server into flash or load it directly into RAM.

Please note that in order to complete this lab youвЂ™ll need a REAL Cisco 2600 Series Router or greater as this lab cannot be emulated on the GNS3 application. After the copy has completed, reboot the router and verify that the image boots successfully.Once all necessary configuration is done copy the IOS image from the TFTP server to the flash.

Once booted into Cisco IOS, configure a router so that you may copy a Cisco IOS image from a TFTP server to Flash.

Execute the TFTPDNLD command and load the image into RAM using the -r switch.

Set the TFTPDNLD variables required to execute the procedure which include IP Address, Subnet Mask, Default Gateway, TFTP Server, TFTP Image name.

Boot the Cisco router into ROM mode by breaking the boot sequence using the keystroke CTRL + Pause Break.
