Usage guidelines
To avoid conflicts, do not use ARP MAD together with LACP MAD in an IRF fabric. However, you can
use ARP MAD together with BFD MAD.
ARP MAD detects multi-active collisions by using extended ARP packets.
You can set up ARP MAD links between neighbor IRF members or more commonly, between each
IRF member device and an intermediate device.
If the intermediate device is also in an IRF fabric, make sure the two IRF fabrics have different IRF
domain IDs to avoid false detection of IRF splits.
You can enter the domain ID when you use the mad arp enable command. If the IRF fabric already
has a unique domain ID in accordance with the network planning, press Enter to skip the step.
The IRF domain ID takes effect on all MDCs.
