Auto-IP DEFEND_INTERVAL (RFC3927) support:
1 =
Upon receiving a conflicting ARP packet, if a host has not seen any other conflicting ARP packets within the last DEFEND_INTERVAL (10) seconds, it attempts to defend its address by recording the time that the conflicting ARP packet was received, and then broadcasting one single ARP announcement, giving its own IP and hardware addresses as the sender addresses of the ARP. Having done this, the host can then continue to use the address normally without any further special action. However, if this is not the first conflicting ARP packet the host has seen, and the time recorded for the previous conflicting ARP packet is recent, within DEFEND_INTERVAL seconds, then the host MUST immediately cease using this address and configure a new IPv4 Link-Local address as described above. This is necessary to ensure that two hosts do not get stuck in an endless loop with both hosts trying to defend the same address.0 = is disabled.
Upon receiving a conflicting ARP packet, a host immediately configure a new IPv4 Link-Local address.
