The bootstrap image processes the initialization parameters from the BOF and attempts to locate the configuration file configured in the BOF. Up to three locations can be configured for the system to search for the configuration file. The locations can be local or remote. The first location searched is the primary configuration location. If not found, the secondary configuration location is searched, and lastly, the tertiary configuration location is searched.
If the configuration file is in a remote location, the bootstrap process saves it on the flash as cf1:/default.cfg. Users must not delete this file or create a file with this name. The configuration file includes chassis, IOM, MDA, and port configurations, as well as system, routing, and service configurations.
Like the configuration file, three locations can be configured for the system to search for the files that contain the both.tim (SR OS/TiMOS) image. The locations can be local or remote. The first location searched is the primary image location. If not found, the secondary image location is searched, and lastly, the tertiary image location is searched.
