Thanks for your answer... The P router is M10i ( 8.2 R2.4) , the PE router is m7i ( 7.3R1.5)Im working with real traffic and there are a lot of application using the links. And the behavior of the hash mechanism could be the reason of what im seeing .. do you know how can i test change the behavior of the algorithm, thanks ..
