Restrictions and guidelines

When an IRF member device splits from the IRF fabric, its settings are retained in memory but removed from the running configuration on the IRF fabric. Saving the running configuration before the IRF fabric recovers will remove the member device's settings from the next-startup configuration file.

If you have saved the running configuration before the member device rejoins the IRF fabric, perform the following steps to restore the member device settings to the next-startup configuration file:

  1. Resolve the split issue.

  2. Reboot the member device to rejoin the IRF fabric.

  3. After the member device rejoins the IRF fabric, execute the display current-configuration command to verify that the member device's settings have been restored from memory to the running configuration.

  4. Save the running configuration to the next-startup configuration file on the IRF fabric.


    [IMPORTANT: ]

    IMPORTANT:

    To ensure a successful configuration restoration, make sure the IRF fabric has not rebooted after the member device left.
