If the value of MAC ADDRESS in an ARP entry is Incomplete, this ARP entry is a temporary one. When IP packets trigger ARP Miss messages, the device generates temporary ARP entries and sends ARP Request packets to the destination network segment.
- When a temporary ARP entry is not aged out:
- Before receiving an ARP Reply packet, the device discards the IP packets matching the temporary ARP entry, and no ARP Miss message is triggered.
- After receiving the ARP Reply packet, the device generates a correct ARP entry to replace the temporary entry.
- After the temporary ARP entry ages out, the device deletes this entry.
