"I had a pleasure of attending Heinz Ulm CCIE BootCamp during a three week period. Heinz is not only one of a kind internetworking expert but also an experienced professor who has great knowledge of not only the principles and technologies but of ways each and every engineer struggles with adopting them. He knows your weak points and attacks them with no mercy! I must say I deeply respect him and admire him! And don't forget: A day without CLI is like a day without sunshine!           CCIE 30037 (Serbia)" CCIE 30037
