Route layer: different results with "same" network datasets

I am using two network datasets:
1. street network dataset covering whole Switzerland
2. a clipped version of above covering only a part of Switzerland

With the two network datasets, I am calculation a route using the same input locations. The results are as follows:
1. With the street network covering whole Switzerland, there are unreached locations
2. With the clipped version everything is fine, there are no unreached locations

I don't understand why there are unreached locations in the larger network because the two street networks are exactly the same in the area of the route (= the clipped area)

Thanks a lot for your answers in advance
