I have two Shapefiles with Polygons ( City and Forerst)
Is there a Plugin who is able check the topology (QGIS)? Like "Knots do not overlap" or something like that? I dont want that they overlap.
Does anybody know a Plugin? Would be great!
The new Topology Checker Plugin will be available in the next release. You can see it at work in this video: http://www.youtube.com/watch?v=huhkTZkoKC8

You can use the GRASS Toolbox for that.
