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.
# Enable the spanning tree feature globally, and map the ARP MAD VLAN to MSTI 1 in the MST
region.

ND MAD-enabled IRF configuration example
Network requirements
As shown in
, set up a two-chassis IRF fabric at the distribution layer of the enterprise network.
•
Configure ND MAD for the IRF fabric and use Device C as an intermediate device. Device C can
come from any vendor.
•
To prevent loops, enable the spanning tree feature between the IRF fabric and Device C.
