Figure 7 ARP MAD application scenario
Each IRF member compares the domain ID and the active ID in incoming extended gratuitous ARP
packets with its domain ID and active ID:
•
If the domain IDs are different, the extended gratuitous ARP packet is from a different IRF fabric.
The device does not continue to process the packet with the MAD mechanism.
•
If the domain IDs are the same, the device compares the active IDs:
{
If the active IDs are different, the IRF fabric has split.
{
If the active IDs are the same, the IRF fabric is integrated.
