Description On a router supporting the dual image function (a Flash larger than 8 MB must be
available), three boot files are defined in the system by default: main boot file, backup
boot file, and secure boot file. The system uses them in the following order:
■ Main boot file, with the default name being main.bin and file type being M, is the
default file for system boot;
■ Backup boot file, with the default name being backup.bin and file type being B, is
the boot file used in case of the boot failure using the main boot file;
■ Secure boot file, with the default name being secure.bin and file type being S, is
the boot file used in case of the boot failure using the backup boot file. If the boot
attempts using all these files fail, the system prompts the boot failure.
This command is only available with the routers that support the dual image function.
