Figure 6 BFD MAD application scenario
ARP MAD
ARP MAD detects multi-active collisions by using extended gratuitous ARP packets that convey the IRF
domain ID and the active ID.
You can set up ARP MAD links between neighbor IRF member devices, or more commonly, between each
IRF member device and an intermediate device (see
Figure
7). If an intermediate device is used, you must
also run the spanning tree feature between the IRF fabric and the intermediate device.
