What you are doing wont work as every machine has to have an individual 
ip address unless your talking multicast

If you are trying to provide some fault tolerance eg two routers you 
should look at using carp. This will aloow you to have a floating ip 
between two or more machines. Only one machine has it at any one time 
though.
