If two IRF fabrics have the same bridge MAC address, they cannot merge.
To configure the IRF bridge MAC persistence setting:
Ste

Command Remarks
1. Enter system view.
system-view N/A
2. Configure IRF bridge MAC
persistence.
• Retain the bridge MAC address
even if the master has changed:
irf mac-address persistent always
• Preserve the bridge MAC address
for 6 minutes after the master
leaves:
irf mac-address persistent timer
• Change the bridge MAC address
as soon as the master leaves:
undo irf mac-address persistent
By default, the IRF fabric's
bridge MAC address is retained
permanently even after the
master leaves.
Enabling software auto-update for system software image
synchronization
The software auto-update function automatically propagates the system software image of the master to
all members in the IRF fabric.
To join an IRF fabric, a device must use the same system software image as the master in the fabric.
When you add a device to the IRF fabric, the software auto-update function compares the system
software versions of the device and the IRF master. If the versions are different, the device automatically
downloads the system software image from the master, sets the downloaded image as the system
software for the next reboot, and automatically reboots with the new system software image to rejoin the
IRF fabric.
If software auto-update is disabled, you must manually update the device with the system software image
of the master.
Configuration prerequisites
Before you use the software auto-update function, verify the following items:
• The device you are adding to the IRF fabric is compatible with the software version running on the
master. If it is not compatible, the automatic system software upgrading function cannot correctly
work.
• The device you are adding to the IRF fabric has sufficient space for the new system software image.
Configuration procedure
