Disable ARP on FreeBSD

Introduction

On FreeBSD, there is an option "-arp" 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.

Disable ARP for VIP

In LVS/DR clusters, we can disable ARP for VIP on FreeBSD as follows:

ifconfig lo0 alias VIP netmask 255.255.255.255 -arp up
