Rohl has a 100% record in the Premiership, with Rangers on their best league run since February.
The tempo may have dropped in the second half but it is evident the new head coach wants to see the ball getting forward quickly.
A series of long diagonal passes had the home defence turning on their heels in the opening exchanges and Rangers soon had two goals to celebrate.
McCracken was kept busy at regular intervals thereafter, stopping shots from Aasgaard and Gassama before showing great reflexes to claw away Raskin’s second free header of the afternoon.
Moore was a menace, drifting into central positions, but Rohl will want to see more from his strikers since Bojan Miovski and half-time replacement Youssef Chermiti were both peripheral figures.
Dundee stay second bottom of the table and have now lost five of their past six matches, with their best effort a well-saved free-kick from Ethan Hamilton in the third minute.
A stunning 2-0 win over an out-of-sorts Celtic is starting to look like an outlier for Steven Pressley’s side.
On that occasion Dundee struck first and fought for their lives, just as they did in a 1-1 draw at Ibrox in August.
The spirit and graft shown in those games was lacking and there was no real cohesion, despite an improvement in the final 25 minutes.
