不知道哪里配的不对，造成用route-map重分发不成功，望高手指点，谢谢

R2 学到的OSPF路由是3.3.3.3/32，33.33.33.33/32这两个IP地址

access-list 1 permit 3.3.3.0 只是匹配3.3.3.0/32这一个地址,并没有匹配3.3.3.3/32

改成access-list 1 permit 3.3.3.3  就匹配了 3.3.3.3/32  这条从OSPF学到的路由

access-list 1 permit 3.3.3.0 0.0.0.255 匹配3.3.3.0-3.3.3.255即3.3.3.0/24
3.3.3.0/24里包含3.3.3.3/32 所以被匹配了


r2#show access-lists
Standard IP access list 1
    20 permit 3.3.3.3 (2 matches) 有匹配IP或路由
    10 permit 3.0.0.0             未匹配IP或路由

通配符是来进行范围的选择
0代表严格固定，不允许变化，1代表可以任何改变（0，1二进制）

R2 上面的ACL没匹配3.3.3.3 和33.33.33.33这两个路由
把
access-list 1 permit 3.3.3.0
access-list 2 permit 33.33.33.0
改成
access-list 1 permit 3.3.3.0 0.0.0.255
access-list 2 permit 33.33.33.0 0.0.0.255

谢谢，可以了，但是我有个问题，为什么教程上是像我这么写的，没有反掩码，也是可以的。
access-list 1 permit 3.3.3.0 0.0.0.255 这样写是不是表示通配符掩码，表示用来匹配范围的是吗？
能不能祥细解释一下
