Prior versions of FRR supported reading and writing per-daemon config files; however, with the introduction of the centralized management daemon `mgmtd` this could no longer be supported.

In order to allow for an orderly transition from per-daemon config files to the integrated config file, FRR daemons will continue to try and read their specific per-daemon configuration file as before. Additionally the config can still be loaded directly using the `-f` or `--config-file` CLI options; however, these files will not be updated when the configuration is written (e.g., with the `write mem` command).

Warning

Per-daemon files will no longer be updated when the user issues a `write memory` command. Therefore these per-daemon config files should only be used as a mechanism for transitioning to the integrated config, and then removed.
