In my office one Router went to Rommon mode.When I give the dir flash: it did't showed any IOS.I used tftpdnld process to upload the IOS.Then it worked fine for 1 day.Next I restarted the Router and again it went Rommon mode.This time when i give the dir flash:,it is not showing the IOS that is present in the falsh.So i tried to the boot the Router with boot flash:iosname.bin but it is giving following error.
bad file magic number and with some other errors it ends with Rommon prompt.
My question is whether it is the problem of the corrupted Flash or IOS?
If it is the flash,to confirm it,is it possible to boot the Router by removing the flash away from Router and booting it with TFTP server?
Please answer my question,I am waiting for all of your valuable suggestions.
Thanks & Regards
