The two devices perform master election, and the one that has failed the election reboots to
form an IRF fabric with the master.

Configure LACP MAD on the IRF fabric:
# Set the domain ID of the IRF fabric to 1.
<Sysname> system-view
[Sysname] irf domain 1
# Create a dynamic aggregate interface and enable LACP MAD.
[Sysname] interface bridge-aggregation 2
[Sysname-Bridge-Aggregation2] link-aggregation mode dynamic

You need to assign a domain ID (range: 0-4294967295)
[Current domain is: 1]:
The assigned domain ID is: 1
Info: MAD LACP only enable on dynamic aggregation interface.

Configure Device E as the intermediate device:
CAUTION:
If the intermediate device is also an IRF fabric, assign the two IRF fabrics different domain IDs
for correct split detection. False detection causes IRF split.

BFD MAD-enabled IRF configuration example (using
crosslink ports)
Network requirements
, set up a two-member IRF fabric.
•
Configure BFD MAD in the IRF fabric and set up BFD MAD links between each member device
and the intermediate device.
•
Disable the spanning tree feature on the ports used for BFD MAD, because the two features
conflict with each other.
