Dave Kearney scored Leinster’s first try
Leinster remain on course to qualify from European Champions Cup Pool Two following a 50-8 bonus point thrashing of Castres at the RDS.
Matt O'Connor's men had chalked up four tries by half-time, with Dave Kearney's second-minute opener followed by further converted efforts from Martin Moore, Eoin Reddan and Sean Cronin.
Moore and Reddan scored their tries while Castres flanker Ibrahim Diarra was in the sin-bin, as the Irish province threw off the shackles having only scored four tries in the previous four rounds.
They added to their 31-3 interval lead with a maiden European try for replacement prop Tadhg Furlong and Darragh Fanning came off the bench to bag his third in this season's tournament.
Castres' only consolation was an unconverted try from Romain Martial, before Luke McGrath made it seven tries on the night for Leinster, whose qualification battle with Harlequins and Wasps is likely to go right down to the wire next week.
