Sean O'Brien goes over for Leinster's third try at the RDS
Four second-half tries gave Leinster a comfortable bonus-point Magners League win at the RDS on Saturday night.
Glasgow led 13-8 at the break thanks to tries from Kelly Brown and Lome Fa'atau while Ricky Elsom went over for the Heineken Cup semi-finalists.
Leinster took control after a testing opening hour and eased to victory.
Shane Horgan's converted touchdown put Leinster ahead before tries from Sean O'Brien (2) and Jonathan Sexton, while Felipe Contepomi kicked 11 points.
The result was immaterial as, after Munster's bonus-point win over the Scarlets on Friday, Leinster's title reign is at an end.
Glasgow were unfortunate not to open the scoring when Ruaridh Jackson watched a penalty attempt slide away.
Contepomi punished a ruck offence from Brown to kick Leinster in front but a huge hit by Moray Low on Contepomi helped the Glasgow forwards pile through and set up Jackson for the levelling kick.
Sean Lineen was forced into an early switch, with Fergus Thomson coming on at hooker for the injured Dougie Hall yet, just moments later, Brown gobbled up a dinked kick through from Jackson to touch down in the right corner.
After the missed conversion, a break from Girvan Dempsey got Leinster within scoring range and off a set lineout move, Devin Toner tapped down to Malcolm O'Kelly and Elsom then peeled away for a short burst to the try-line.
Contepomi failed to add the extras, leaving it 8-8, and he also pushed a penalty wide of the uprights on the half-hour after a thunderous tackle from Jamie Heaslip on Bernardo Stortoni.
Then Samoan speedster Fa'atau pounced for his try, brilliantly hacking a dropped Leinster pass on towards the line and winning the race to the ball.
Jackson was off target with the conversion attempt.
Shortly afterwards, Stortoni was sin-binned for slowing up Leinster ball close to his posts.
Leinster gradually found their rhythm in the third quarter.
Contepomi missed another penalty chance but they continually pinned back Glasgow in their half and the pressure eventually yielded tries.
After Brown and Heaslip were sin-binned for throwing punches, Leinster made use of the extra space and a quick turnover allowed Sexton to send Horgan galloping over for his try.
Contepomi made it a seven-pointer, putting Leinster back in front, and four minutes later Girvan Dempsey pumped his legs out of a tackle and lovely hands from O'Driscoll put O'Brien charging over behind the posts.
After Contepomi's conversion, Glasgow had a third player sin-binned when eplacement prop Justin Va'a was caught on the wrong side of a ruck.
With the visitors caught for defenders, Sexton gathered a swift delivery from hris Whitaker to dive over to the right of the posts and O'Brien rumbled over from close range for his second try, six minutes from the end.
Contepomi converted both to wrap up a runaway win.
