HP FlexFabric 12500 Series Configuration Manual page 48

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.
