Below are the steps to follow for copying the Cisco IOS software image from a router acting as TFTP server to another router. 1. Check the image size on Router1 with the show flash command. 2. Check the image size on Router2 with the show flash command to verify if enough space is available on Router2 for the system image file to be copied. 3. Configure Router1 as the TFTP server: Router1(config)#tftp-server flash:/c2500-js-l.122-10b 4. When the TFTP server is configured, download the specified image from Router1 to Router2 using the copy tftp flash command.
