I was wondering if the startup for ISR routers are stored on the compact flash?
Reason being say for example my 2811 router fails, would I be able to eject the compact flash and insert it into another 2811 router and all is well? I can replace the defective one with this one?
The startup config is on the NVRAM. The answer is no, you will have to manually copy it to the flash. A good practice is always back it up to a common network drive like TFTP/FTP server.
