Step
10. Assign the interface an IP
address.
11. Enable ARP MAD.
Configuring ND MAD
When you configure ND MAD, follow these guidelines:
• Do not use the VLAN configured for ND MAD for any other purposes.
You cannot enable ND MAD on VLAN-interface 1.
•
If an intermediate device is used, you can use common data links as ND MAD links. If no
•
intermediate device is used, set up dedicated ND MAD links between IRF member devices.
If an intermediate device is used, make sure the following requirements are met:
•
Run the spanning tree feature between the IRF fabric and the intermediate device.
Enable the IRF fabric to change its bridge MAC address as soon as the master leaves.
Create a ND MAD VLAN and assign the ports on the ND MAD links to the VLAN.
If the intermediate device is also an IRF fabric, assign the two IRF fabrics different domain IDs
for correct split detection.
To configure ND MAD:
Step
1. Enter system view.
2. Assign a domain ID to the IRF
fabric.
3. Configure the IRF bridge
MAC address to change as
soon as the master leaves.
4. Create a VLAN dedicated to
ND MAD.
5. Return to system view.

By default, ARP MAD is
disabled.
When you use the mad arp
enable command, the system
prompts you to enter a domain
ID. If you do not want to change
the current domain ID, press
enter at the prompt.
Remarks
N/A
The default IRF domain ID is 0.
By default, the IRF fabric's
bridge MAC address persists
permanently after the master
leaves.
The default VLAN on the device
is VLAN 1.
