When configuring ssh on a router and it creates the keys etc.. . I don't see anything in the config that indicates ssh was enabled other than the vty "transport" parameters . Say you had to replace a router and you use a backup tftp file to config the box how does it know to create the key if there is nothing in the config file to tell it to do this . Is this a manual process if you have to replace the box where you have to add the "crypto key generate rsa" command ? Somehow it knows over reboots to config a key I just don't see anything in the config to tell it to do that . Trying to get a process down if equipment has to be replaced. Is placed somewhere in nvram in a different filename ??
