902实验题eigrp stub疑问

hinswan

题库最后那里写着有

The success of pings from R4 to the R3 LAN interface proves that the fault has been corrected
and the R3 IP routing table only contains two 10.0.0.0 subnets


意思就是说10.0.0.0的子网只能有2个吧？

但是实验里面貌似没这个

我按照题库里面gns3的拓扑实验题

最后R3的路由器显示是



但是下面又解释说
But in your real exam, if you see the line “10.0.0.0/8 is a summary,….Null0″ then you need to
summary using the network 10.0.0.0/8 with the command “ip summary-address eigrp 123
10.0.0.0 255.0.0.0″ . This configuration is less optimize than the first but it summaries into 2
subnets as the question requires (maybe you will not see this case, don’t worry!).
The command “copy running-config startup-config” will not work so try using this command;
just skip if it doesn’t work.


意思大概把汇总地址换成  ip summary-address eigrp 123  10.0.0.0 255.0.0.0  ??因为我实验里面显示了10.0.0.0指向null 0
然后我把汇总地址敲成ip summary-address eigrp 123  10.0.0.0 255.0.0.0   
后面的结果就是，r2 ping不通r3 !!! 因为r3的汇总地址10.0.0.0的地址指向null 0
如果换成ip summary-address eigrp 123  10.2.0.0 255.255.0.0 就正常，但是此时有3个10.0.0.0的子网不符合题意。。求解。。谢谢
