Configuring IRF bridge MAC persistence
Depending on the network condition, enable the IRF fabric to retain or change its bridge MAC address after the address owner leaves. Available options include:
irf mac-address persistent timer—Bridge MAC address of the IRF fabric is retained for 6 minutes after the address owner leaves. If the address owner does not return before the timer expires, the IRF fabric uses the bridge MAC address of the current master as its bridge MAC address. This option avoids unnecessary bridge MAC address changes caused by device reboot, transient link failure, or purposeful link disconnection.
irf mac-address persistent always—Bridge MAC address of the IRF fabric does not change after the address owner leaves.
undo irf mac-address persistent—Bridge MAC address of the current master replaces the original IRF bridge MAC address as soon as the owner of the original address leaves.
