I would like to know if any one can device a solution for this challenge.
Rules of the game: It must be solved using IOS configuration parameters.
Here is the challenge:
On any given CISCO IOS switches, make the switch send back the exact packet you have just sent, to and from the same physical port.
Some people believe it is impossible to do that, but I would like to know if there are any one out there that can prove this theory wrong, can a Cisco switch be flexible enough to do that?
