Behind Leinster in the Group A standings are Ulster, who came from behind to overcome lowly Zebre 22-7 in Friday's other match.
Leinster and Glasgow Warriors both ran in 50 points as they claimed emphatic Pro14 victories over the Dragons and Southern Kings respectively.
Group A leaders Leinster have made a fantastic start to the season and continued their fine form with a 50-15 triumph at the RDS Arena to make it five wins from five.
Michael Bent started things off early for Leinster, who never looked likely to relinquish their lead over the Dragons, which stood at 19-8 by half-time.
Harry Byrne – on his first Leinster start – also got in on the act, with the fly-half also kicking five conversions, with tries from Dave Kearney, Ronan Kelleher and James Lowe setting the stage for Hugh O'Sullivan's double to complete the rout.
Glasgow, meanwhile, will be hoping their 50-0 demolition of Southern Kings can kick-start what has been an indifferent campaign so far.
Warriors coach Dave Rennie has been identified by New Zealand as a possible replacement for Steve Hansen, but three defeats out of four matches had left Glasgow languishing in the lower reaches of Group A.
Rennie's side responded in force, however, running in five tries in the first half before adding a further three – including a penalty try – after the restart as their South African opponents wilted.
