4. Configure ARP MAD:
# Create VLAN 3, and add port GigabitEthernet 1/4/0/2 (located on Device A) and port
GigabitEthernet 2/4/0/2 (located on Device B) to VLAN 3.
<Sysname> system-view
[Sysname] vlan 3
[Sysname-vlan3] port gigabitethernet 1/4/0/2 gigabitethernet 2/4/0/2
[Sysname-vlan3] quit
# Create VLAN-interface 3, assign it an IP address, and enable ARP MAD on the interface.
[Sysname] interface vlan-interface 3
[Sysname-Vlan-interface3] mad arp enable
You need to assign a domain ID (range: 0-4294967295)
This command will enable ARP MAD on the VLAN interface. Continue? [Y/N]: Y
[Current domain is: 1]:
The assigned domain ID is: 1
[Sysname-Vlan-interface3] ip address 192.168.2.1 24
5. Configure Device C as the intermediate device:
IMPORTANT:
If the intermediate device is also an IRF fabric, assign the two IRF fabrics different domain IDs for
correct split detection. False detection causes IRF split.
# Enable the spanning tree function globally on Device C.
<DeviceC> system-view
[DeviceC] stp enable
# Create VLAN 3, and add port GigabitEthernet 4/0/1 and port GigabitEthernet 4/0/2 to VLAN
3.
[DeviceC] vlan 3
[DeviceC-vlan3] port gigabitethernet 4/0/1 gigabitethernet 4/0/2
[DeviceC-vlan3] quit
Restoring standalone mode
Network requirements
Dismantle the IRF fabric in Figure 20 , and change the operating mode of Device A and Device B from IRF
to standalone.
