If I try to do this I get the following:

bash-3.2# ifconfig tun0 10.140.1.40
ifconfig: ioctl (SIOCAIFADDR): Destination address required

It sounds like this doesn't happen in Linux (probably this is a BSD thing). The problem is I need to have a generic tun interface without a specific destination address because I am trying to do LVS-TUN like in this example but I need to use an OSX real server (strange I know).

What is the way to implement a ipip virtual interface on OSX?

What leads you to believe that something called Linux Virtual Server would run on an OSX box? –  Zoredache Jan 5 '13 at 1:24
    
what makes you believe it wouldn't? –  Doug Jan 5 '13 at 9:43
    
The simple and obvious fact that Mac OS X is not Linux. –  Michael Hampton Jan 5 '13 at 22:19
    
Its called Linux Virtual Server because it runs on Linux, not because the clients must be Linux. Do you need a Linux mail client to retrieve your email from a Linux server? This is some holier than thou ish if you ask me. –  Doug Jan 6 '13 at 22:10

figured it out -- it is WAY easier to use LVS-DR method with OSX. It turns out disabling ARP for an interface is very simple in OSX and BSD. One command gets you online:

ifconfig lo0 alias VIP netmask 255.255.255.255 -arp up
