If the IRF fabric is integrated, only the MAD IP address of the master takes effect. The master
cannot establish a BFD session with any other member. If you execute the display bfd
session command, the state of the BFD sessions is Down.
•
When the IRF fabric splits, the IP addresses of the masters in the partitioned IRF fabrics take
effect. The masters can establish a BFD session. If you execute the display bfd session
command, the state of the BFD session between the two devices is Up.
Examples
# Assign a MAD IP address to IRF member 1 on VLAN-interface 3.
<Sysname> system-view
[Sysname] interface vlan-interface 3
[Sysname-Vlan-interface3] mad ip address 192.168.0.1 255.255.255.0 member 1
# Assign a MAD IP address to IRF member 2 on VLAN-interface 3.
[Sysname-Vlan-interface3] mad ip address 192.168.0.2 255.255.255.0 member 2

differently.
When you configure ND MAD on a VLAN interface, follow these restrictions and guidelines:

If you are using an intermediate device, perform the following tasks:
On the IRF fabric and the intermediate device, create a VLAN for ND
MAD.
On the IRF fabric and the intermediate device, assign the ports of ND
MAD links to the ND MAD VLAN.
On the IRF fabric, create a VLAN interface for the ND MAD VLAN.
