Parameters
domain-id: Specifies an IRF MAD domain ID. The value range is 0 to 4294967295.
Usage guidelines
An IRF MAD domain ID uniquely identifies an IRF multi-active detection domain. If the IRF fabric
uses another IRF fabric as the intermediate device for LACP MAD, ARP MAD, or ND MAD, you must
assign the two IRF fabrics different MAD domain IDs for correct split detection. False detection
causes IRF split.
An IRF fabric has only one IRF MAD domain ID. You can change the IRF MAD domain ID by using
the irf domain, mad enable, mad arp enable, or mad nd enable command. The IRF MAD domain
IDs configured by using the commands overwrite each other.
Example
# Set the IRF MAD domain ID to 10.
<Sysname> system-view
[Sysname] irf domain 10
irf mac-address persistent
Use irf mac-address persistent to configure IRF bridge MAC persistence.
Use undo irf mac-address persistent to enable the IRF fabric to change its bridge MAC address as
soon as the address owner leaves.
Syntax
irf mac-address persistent { always | timer }
undo irf mac-address persistent
Default
The IRF bridge MAC address remains unchanged for 6 minutes after the address owner leaves the
IRF fabric.
