### Disable IP_Forward in Linux Kernel ###

### Disable ARP Reponse on This RealServer ###

### Add VIP Address and Route ###
VIP=172.16.1.50

/sbin/ifconfig lo:0 $VIP broadcast $VIP netmask 255.255.255.255 up
/sbin/route add -host $VIP1 dev lo:0
			

我比較喜歡使用ip命令代替route命令

ip route add $VIP dev lo:0 src $VIP
