Leinster put in another impressive performance and went to the top of the Heineken Cup standings when they beat Montpellier 25-3 at the RDS.
The only downside on Leinster's performance was that they failed to score the fourth try which could have earned them an extra point.
The result does however ensure that Leinster will have an home Heineken Cup quarter-final.
Leinster had already qualified for the Heineken Cup quarter-finals but they kept their unbeaten record in Pool 3 with this comfortable win.
The reigning champions, who lifted the trophy for the second time in last season's epic final over Northampton Saints at the Millennium Stadium in Cardiff, had already qualified for the knockout stages last weekend.
But this impressive victory over a Montpellier side, who had nothing to play for but pride at the RDS, stretched Leinster's unbeaten record in the Heineken Cup to a dozen matches.
Leinster fly-half Jonathan Sexton was a late withdrawal just before kick-off with a recurrence of his ankle injury and was replaced by Ian Madigan, starting his first Heineken Cup game, but it hardly had an impact on the home side.
The hosts soon established their superiority and had scored a point a minute when they took an early lead of 17-0 after 17 minutes of this contest, with tries by flanker Sean O'Brien and full-back Rob Kearney and the boot of wing Fergus McFadden.
The Irish province went down to 14-men when they lost second row Damian Browne midway through the first half for a professional foul but despite immense Montpellier pressure the home side didn't concede a point.
McFadden added his second penalty to stretch Leinster's lead to 20-0 at half-time but soon extended their lead just after the break when prop Cian Healy barged over from short-range.
Wing Martin Butos Moyano did manage to get the visitors on the scoreboard with a penalty on the 67th minute but that was all they had to show despite having their periods of pressure and dominance in the game.
