Munster's Paul Warwick is blocked by James Marshall and Fabio Staibano
Munster consolidated their position as runaway Magners League leaders by seeing off Italian hosts Aironi at Stadio Zaffanella.
The Irish province prevailed thanks to lock Donnacha Ryan's touchdown and a penalty try, while Paul Warwick booted two penalties and both conversions.
Aironi gained a consolation score through their forward Nick Williams. Munster, though, were never in danger of being unsettled in their relentless push towards the title play-offs.
Ryan, meanwhile, was one of three players who collected yellow cards, with Aironi wing Guilio Toniolatti and flanker Gareth Krause also cautioned.
