This command will enable LACP MAD on the aggregate interface. Continue? [Y/N]: Y
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 C as the intermediate device:
IMPORTANT:
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.
# Create a dynamic aggregate interface.

# Assign ports GigabitEthernet 4/0/1 and GigabitEthernet 4/0/2 to the dynamic aggregate
interface.

When the IRF links fail, the system outputs IRF link problem and card failure error messages.
Because it has a lower member ID than Device A, Device B transits to the Recovery state and shuts
down all its ports except those excluded from the shutdown action.
BFD MAD-enabled IRF configuration example
Network requirements
Set up an IRF fabric at the distribution layer of the network as shown in
.
Configure BFD MAD in the IRF fabric and set up BFD MAD links between the member devices.
Disable the spanning tree feature on the ports used for BFD MAD, because the two features conflict with
each other.
Assign the highest member priority to Device A so it can be elected the master.
