Check out the following output from my router running Cisco IOS. It is displaying an unusual prompt to issue IOS commands even though its hostname as determined by using the "show running-config" command is simply "Router". How was this achieved?
MYSTERY_PROMPT$show running-config | include hostname
hostname Router
MYSTERY_PROMPT$
