Leinster extended their winning run over Munster with a 30-22 victory over their rivals at the Aviva Stadium.
James Lowe scored twice for the hosts with the rest of the points coming from the boot of Ross Byrne and a penalty try.
Munster were made to work very hard for tries from Tadhg Beirne, CJ Stander and Alby Mathewson and the Guinness Pro14 champions held the visitors at arm's length for large spells of the game.
The Reds have not got the better of Leinster since December 2016 but can take some solace from their best away performance of the season ahead of the start of the Champions Cup next weekend.
Leo Cullen's men will be happy with their showing in front of 50,120 ahead of the RDS clash with Wasps on Friday.
For all the talk of resting players ahead of next week's games, Leinster, even without Johnny Sexton, had 12 full Ireland internationals in the starting XV.
Munster, with more ground to make up ahead of the trip to Exeter, lined out with just four non-Ireland caps.
Sean O'Brien was making his first start of the season, as was Jack McGrath in the Leinster pack.
It was the hosts who settled first and when Keith Earls and Andrew Conway got into a muddle over a high ball, the lively Lowe hoovered up the loose ball.
Leinster worked their way up to the line and the ref, after a TMO consultation, judged that Earls tackled the Kiwi without the ball, binned the Ireland wing and ran under the posts to signal a penalty try.
Just four minutes later Lowe managed to get his name on the scoresheet, showing superb finishing skills to dot down in the corner, brushing off Alby Mathewson and Niall Scannell in the act.
Back came Munster, winning a series of penalties before the pack drove Tadhg Beirne over the line; Carbery, against his old side, couldn't add the conversion but it was game on.
The out-half, however, was becoming more influential in play and helped Munster to find the field position to allow Stander to drive over for their second try in an eight-minute spell.
"The Munster pack are giving Carbery a platform to perform," said Tomas O'Leary, on analysis duty with RTE Radio 1's Saturday Sport, as the former Leinster man split the posts.
Johann van Graan will have been frustrated to subsequently see his charges waste valuable possession and territory before the half-time whistle, a spell which yielded two Byrne penalties, and left the score at 20-12.
"A ridiculous decision," according to Shane Byrne on Saturday Sport, led to Leinster's third try straight after the break as the touchjudge called a deliberate knock on against a Munster centre.
From the resulting penalty the forwards worked through the phases, making space outside for Lowe to grab his second, angling his body perfectly to avoid the covering tackles.

At this stage the penalty count was 8-2 in the Pro14 champions' favour, a solid blue line absorbing the Munster runners without losing their discipline.
But that was soon to change as the concession of seven penalties in a row allowed Carbery to reduce the deficit by three points before Mathewson evaded the defence to grab his first score for the club.
That made it 27-22 with 12 minutes to play but a senseless obstruction by Stephen Archer on the restart handed Byrne, who limped out of the action shortly afterwards, a chance to move the Champions Cup holders' lead out to two scores.
The offence was "almost criminal" said O'Leary and the out-half didn't miss.
Munster tried their best to grab a score that would have made for an interesting end game but, try as they might, couldn't breach the line.
