The Bulls reached the quarter-finals of the Champions Cup for the first time ever after they thrashed Lyon 59-19 in Pretoria on Saturday.
Jake White says his Bulls players must learn from the defeat and accept the result after suffering a tough loss against a hugely experienced Leinster side in Ireland.
Player-of-the-match Jack Conan was one of five second-half try scorers for Leinster in a dominant 47-14 United Rugby Championship (URC) win over the Bulls at the RDS.
