The problem with ONI and MP<whatever>S models is that there is little 
or no correlation between the topology aware layers. You will most 
likely sooner or later end up in a situation where the layers will 
start to oscillate.

So, I would not build a optical IX around this model - if I would build 
a optical IX at all.
