### Description

A consistent reduction ansatz of eleven-dimensional supergravity to $N=2$ $SO(4)$ seven-dimensional gauged supergravity is constructed. The resulting seven-dimensional theory admits a topological mass term for the three-form field and a maximally supersymmetric $AdS_7$ critical point. This is in contrast to the gauged supergravity without topological mass admitting a half-supersymmetric domain wall vacuum. The $AdS_7$ critical point corresponds to $N=(1,0)$ superconformal field theory in six dimensions according to the AdS/CFT correspondence. The reduction ansatz is obtained from a truncation of the consistent $S^4$ reduction giving rise to the maximal $N=4$ $SO(5)$ gauged supergravity, so the consistency is guaranteed by the consistency of the $S^4$ reduction.
