problem in faking DIP for VS-DR

["ÀÌÁ¾±Ç" <conan@xxxxxxxxxxxxxxxxxxx>]

Let's see the following fig. for VS-DR.
Here I want to put another directer for HA.
If I use heartbeat, faking VIP of eth0 of director will be done
automatically.
But, I should also fake the DIP of eth1 of director.
Can I put some script to do this somewhere ? Is there any simple way ?
I think the same situation will arise when we put firewalls in the position
of director and configure HA.
