Configuration synchronization

IRF uses a strict running-configuration synchronization mechanism. In an IRF fabric, all chassis get and run the running configuration of the master. Any configuration change is automatically propagated from the master to the other member devices. The configuration files of these devices are still retained, but these files do not take effect. The devices use their own startup configuration files only after they are removed from the IRF fabric.
