<Sysname> save
# Connect the two devices as shown in
# Log in to Device B. (Details not shown.)
# Enable IRF mode.

[Sysname] chassis convert mode irf
The device will switch to IRF mode and reboot.
You are recommended to save the current running configuration and specify the
configuration file for the next startup. Continue? [Y/N]:y
Do you want to convert the content of the next startup configuration file
flash:/startup.cfg to make it available in IRF mode? [Y/N]:y
Now rebooting, please wait...
Device B and Device A form an IRF after Device B reboots.
3. Configure ND MAD on the IRF fabric:
# Enable the spanning tree feature globally, and map the ND MAD VLAN to MSTI 1 in the MST
region.
<Sysname> system-view
[Sysname] stp global enable
[Sysname] stp region-configuration
[Sysname-mst-region] region-name ndmad
[Sysname-mst-region] instance 1 vlan 3
[Sysname-mst-region] active region-configuration
[Sysname-mst-region] quit
# Configure the bridge MAC address of the IRF fabric to change as soon as the address owner
leaves.
[Sysname] undo irf mac-address persistent
# Set the domain ID of the IRF fabric to 1.
[Sysname] irf domain 1
# Create VLAN 3, and add FortyGigE 1/2/0/2 and FortyGigE 2/2/0/2 to VLAN 3.
[Sysname] vlan 3
[Sysname-vlan3] port fortygige 1/2/0/2 fortygige 2/2/0/2
[Sysname-vlan3] quit
# Create VLAN-interface 3, assign it an IP address, and enable ND MAD on the interface.
[Sysname] interface vlan-interface 3
[Sysname-Vlan-interface3] ipv6 address 2001::1 64
[Sysname-Vlan-interface3] mad nd enable
You need to assign a domain ID (range: 0-4294967295)
[Current domain is: 1]:
The assigned domain ID is: 1
4. Configure Device C as the intermediate device:
CAUTION:
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.
