{ Enable the IRF fabric to change its bridge MAC address as soon as the master leaves. 
{ Create the ARP MAD VLAN and assign the ports on the ARP MAD links to the VLAN.  
{ If the intermediate device is in an IRF fabric, as sign this fabric a different domain ID than the 
ARP MAD-enabled fabric to avoid false detection of IRF partition.

 CAUTION: 
Excluding a VLAN interface and its Layer 2 ports from the shutdown action introduces IP collision risks 
because the VLAN interface might be active on both th
e IRF fabric in Active state and the IRF fabric in 
Recovery state.

To manually recover an IRF fabric in Recovery state:  
Step Command 
1.  Enter system view.

2.  Change the state of the IRF fabric from 
Recovery to Active.  mad restore 
 
After the IRF fabric is recovered, all ports that have been shut down by MAD automatically come up.
