The files managed by the router are of 3 types:
Boot ROM file
Application file (main software)
Configuration file
The router software maintenance mainly refers to the maintenance of those three
types of files, including upgrade and download of Boot ROM and application files,
as well as upload and download of configuration file.
This section introduces the Boot menu, which is used during the software
maintenance of a router.

configuration through CON port, and then start the router. When the
configuration terminal prompts the information "Press Ctrl-B to enter Boot
Menu", press <Ctrl+B>. Then the system prompts the information:

process, reboot the router.
