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-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.

Usage guidelines
Do not configure ND MAD together with LACP MAD or BFD MAD, because they handle collisions
differently.
When you configure ND MAD on a VLAN interface, follow these restrictions and guidelines:
Category Restrictions
and
guidelines
ND MAD VLAN
•
Do not enable ND MAD on VLAN-interface 1.
•
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.
•
If no intermediate device is used, connect each IRF member device to all
other member devices.
