Unbeaten Leinster knocks Montpellier out
Last year's semifinalists Leinster started strongly and took the lead after a thrilling line break by James Lowe enabled Ross Byrne to dot down in the corner. He missed the conversion but soon added a penalty.
There was little happening for Montpellier until two quick-fire tries, both stemming from line-outs.
Bismarck Du Plessis drove over in a maul, then Yacouba Camara crossed after a nice offload by Louis Picamoles.
The hosts had their tails up at half time, but never looked like getting the two further tries they needed to secure a bonus point and keep their quarter-final chances alive. Robbie Henshaw's try was swiftly followed by a Ross Byrne penalty which restored Leinster's lead.
From a five-metre line-out, the Irishmen then scored again, James Ryan's wonderful handling allowing Sean Cronin to dive over.
That was the way it stayed as the visiting defence looked impenetrable against a fading Montpellier challenge.
