I don't know if there will be problems as you actually approach the 1012 node limit. We set ours from 1-10 to allow LOTS of room. > How about 10-13?

The documentation for my FastPath warns that the range should not be *too* big, because each network number uses another quantum of memory in the router. I don't know what kind of routers you're using and if they would have memory problems with this, but 128 networks is clearly excessive for 1000 nodes.
