Scotland's Simon Danielli was the hero for Ulster, running in two early tries to secure a 15-10 Magners League victory over fourth-placed Munster at Ravenhill.
The 30-year-old has found his international opportunities limited since joining Ulster in 2007.
But he returned to the international fold last February with a man-of-the-match display and a try in the RBS 6 Nations match against Italy.
And after a two-try salvo he is sure to have caught the eye of current Scotland coach Andy Robinson as the countdown to this season’s competition continues.
Despite early Munster pressure Ian Humphries put Ulster ahead with the boot before Danielli capitalised on a Paul Warwick mistake to score his first after 11 minutes.
The winger crossed for the second time just 12 minutes later after good work by Andrew Trimble left him with space to score.
Jean De Villiers then scored the try that Munster’s pressure deserved after Ian Humphreys failed to hold on to possession at a turn-over.
Warwick added the extras with the boot before cutting Ulster’s lead to five with a penalty before the break.
Munster were again guilty of losing concentration in defence when Warwick and Dennis Hurley both left the ball but Paddy Wallace was adjudged to have knocked the ball on in what was a massive let off for the visitors.
Despite Warwick hitting the woodwork from a penalty both sides cancelled each other out with most of the second half action taking place in the middle of the park.
