The interfaces that canlearn gateway/peer address dynamically can use value 0.0.0.0 insteadof the next hop address.5.2.3 File system and downloading new firmware using TFTPM1112 has a flash file system. Some files in the file system havespecial meanings. These files are: image.exe; primary application file. image.bak; secondary application file used if image.exe has beencorrupted or is missing. It is then renamed as image.exeautomatically. startup.cfg; primary configuration file used during startup. dhcp.leases; contains DHCP lease table information.M1112 has the following commands that can be used for file handling: copy rename delete dirIf you use image.exe as a destination filename with the copy commandand the image.exe already exists, the existing image.exe will beautomatically renamed as image.bak. This guarantees that theapplication file exists if M1112 loses power during SW download.You can update the operating software of M1112 by downloading thenew software from a TFTP server.
