Hi William,

I think you can do so if after connecting back to back and assigning ip on serial interface if you are able to ping your tftp server.

I think you will be connecting your tftp server on 2621 router ethernet interface? If yes just assign a static route on your 2500 to point to the ethernet of the 2621 router exiting via serial interface of 2500.

Try that and update if it works.
