er.....Sorry about that! I Think i make a mistake, I did no see two same routes from two different routing protocols. in fact, one is "61.168.0.0",another is" 161.168.0.0" . really sorry for put so much trouble on you. everything comes from my experiments's wrong result. the wrong result comes to the wrong conclusion.
so ,really thanks a lot , Zomber and Fred. for pointing out my mistake, so i can get a chance to learn more.
