QGIS 2.8.2 Road Graph doesn't accept road network vector

I'm using the Finnish official Department of Transport's "digiroad" road network vector file, which has all kinds of roads, cycle paths etc on it, but I can't use Road Graph on it.

If I create a new line vector and draw some lines, I can use Road Graph on it.

I don't see how the digiroad is different, other than having several different types of roads. Why can't Road Graph utilize it (it doesn't even let me choose it)?

I'm a beginner, but I've used the same material before on arcgis.
