大神帮忙解答一下这个题

Refer to the exhibit. After redistribution is enabled between the routing protocols; PC2, PC3, and PC4 cannot reach PC1. Which action can the engineer take to
solve the issue so that all the PCs are reachable?


A. Set the administrative distance 100 under the RIP process on R2.
B. Filter the prefix 10.1.1.0/24 when redistributed from OSPF to EIGRP.
C. Filter the prefix 10.1.1.0/24 when redistributed from RIP to EIGRP.
D. Redistribute the directly connected interfaces on R2.
Correct Answer: B


这道的R2是rip协议和eigrp协议互相redistribution还是三个协议互相redistribution呢？如果是两个协议互相redistribution为什么会ping不通PC1，如果是三个协议互相redistribution为什么会ping不通PC1?

感觉这道题出的真是垃圾，这个拓扑只在某些情况下会造成PC2/PC3/PC4 ping不通PC1，比如redistribute的时候metric设置极其不合理，大部分情况下这个拓扑就是能通的。而且这个题的答案也不应该是B。
