Router as a TFTP server

Shaun needed an extra TFTP server in CCNP labs and asked whether you could use a router to act as one. The read-only (download only) TFTP functionality has been available in Cisco IOS for a long time, but the common wisdom was that you could only use the TFTP server function to serve current IOS image.

Fortunately, as of IOS 11.0, the function is more generic; you can serve any file residing on the router (you still cannot upload files), but you have to declare each file to be served with the tftp-server path global configuration command. You could even specify an alias to have the file available under a different name and attach an access list to each configured file to restrict its availability.
