&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== Introduction ==&lt;br /&gt;
&lt;br /&gt;
On FreeBSD, there is an option &amp;quot;-arp&amp;quot; of ifconfig to enable or disable the use of the [[ARP]] protocol on an interface, so it's very convenient to disable ARP for [[LVS]] clusters.&lt;br /&gt;
&lt;br /&gt;
== Disable ARP for VIP ==&lt;br /&gt;
&lt;br /&gt;
In [[LVS/DR]] clusters, we can disable ARP for VIP on FreeBSD as follows:&lt;br /&gt;
 ifconfig lo0 alias VIP netmask 255.255.255.255 -arp up&lt;br /&gt;
&lt;br /&gt;
