If an intermediate device is used, you can use common data links as ARP MAD links. If no
•
intermediate device is used, set up dedicated ARP 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. Make sure
there is only one ARP MAD link in forwarding state. For more information about the spanning
tree feature and its configuration, see Layer 2—LAN Switching Configuration Guide.
Enable the IRF fabric to change its bridge MAC address as soon as the address owner leaves.
Create an ARP MAD VLAN and assign the ports on the ARP 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 ARP 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 address owner
leaves.
4. Create a VLAN dedicated to
ARP MAD.
5. Return to system view.
6. Enter Ethernet interface view.
7. Assign the port to the ARP
MAD VLAN.
8. Return to system view.
9. Enter VLAN interface view.
10. Assign the interface an IP
address.
11. Enable ARP MAD.

Remarks
N/A
The default IRF domain ID is 0.
By default, the IRF fabric's
bridge MAC address remains
unchanged for 6 minutes after
the address owner leaves.
The default VLAN on the device
is VLAN 1.
N/A
N/A
The link type of ARP MAD ports
can be access, trunk, or hybrid.
The default link type of a port is
access.

By default, no IP address is
assigned to any VLAN interface.
By default, ARP MAD is
disabled.
