+ To put it simply, you should not mix Isolation and Route Filtering.
+ It will work, of sorts, but you will not get the expected results. If
+ you are using Isolation sucessfully at the moment, do not get involved
+ in Route Filtering unless you have a good supply of aspirin! Once you
+ have started down the road of Route Filtering, do not use Isolation
+ either. Use one or the other, not both.
