If you are doing it this way, you aren't using bonding at all. You'd  
be splitting the load over three different cards, probably by  
segmenting your network.
Doing this requires editing certain config files to make this work.

This https://fedorahosted.org/k12linux/wiki/MixedNetworkSetup page  
will give you an idea what files need to be changed. You need all the  
services to run on all three nics taht are serving clients.
