This feature is available only when the device is operating in standalone mode. To synchronize software
from the global active MPU to other MPUs on an IRF fabric, use the irf auto-update enable command. For
more information about software auto-update, see IRF Configuration Guide.
When the standby MPU starts up, this feature examines its startup software images for version
inconsistency with the current software images on the active MPU.
If the software versions are different, the standby MPU does the following:
