Device D reboots to join the IRF fabric. A four-chassis IRF fabric is formed.
Configure BFD MAD:

Configure Device E as the intermediate switch:

Add all ports for BFD MAD on Device E to the VLAN dedicated to BFD MAD. (Details not shown.)
IRF split detection and recovery with BFD MAD:
7.
A ring-topology IRF fabric changes to a daisy chain topology when one IRF link fails, and splits
when two IRF links fail.
If both the IRF link between Device A and Device B and the IRF link between Device C and Device
D fail, the IRF fabric splits into two IRF fabrics: IRF 1, which comprises Device A and Device C, and
IRF 2, which comprises Device B and Device D.
When the split is detected, the system outputs an IRF link state and card failure error message. The
following is the sample error message for IRF 1:
