sybex书的135页的一个实验： 我照着他的配置去配，但是最后发现D不能到达A，当我在Routerc上的router ospf 24中加入这句：redistribute rip subnet后，D 就可以到达A 了，我看了一下前后的d的路由表是一样的，请问为什么呢？RouterA interface Ethernet0 ip address 10.1.1.1 255.255.255.0 ! interface Ethernet1 ip address 10.1.2.1 255.255.255.0 ! router ospf 24 network 10.0.0.0 0.255.255.255 area 0

RouterD的路由表： Gateway of last resort is not set
