We present the study of the solar wind interaction with the super-Alfvénic magnetized interstellar medium in the controversial case when fast magnetosonic shocks are nonevolutionary, while admissible switch-on shocks cannot exist due to geometrical reasons. The flow behaviour and the accompanying shock configuration are investigated both in the two-dimensional axisymmetric and 2.5-dimensional, that is, permitting rotation around the symmetry axis, statements. General questions of the origin of nonevolutionary MHD shocks are discussed.
