This object holds the filename used by the Frame Relay (FR) process to read and write its permanent configuration database records, defaulting to '@file://FrFile.cfg' if left as an empty string. An administrator sets this to point the FR subsystem at a specific configuration file, useful when managing multiple named configuration profiles on the same device. For example, setting usrfrBaseCfgFileName to a custom filename lets an admin switch the FR process to load a different saved configuration set than the default.
