By default, the domain ID of an
IRF fabric is 0.
3.

6.
Assign the port or the range
of ports to the BFD MAD
VLAN.
•
Assign the port to the VLAN as
an access port:

member device on the VLAN
interface.
Configuring ARP MAD
Before you configure ARP MAD, choose an ARP MAD link scheme as described in "
As a best practice, connect the ARP MAD links after you finish the ARP MAD configuration if you are
not using existing data links as ARP MAD links.
When you configure ARP MAD, follow these restrictions and guidelines:
