A network administrator is troubleshooting a redistribution of RIP routes into OSPF. Given the exhibited
configuration commands, which statement is true?
router rip

    network 10.0.0.0
!
router ospf 5
    network 172.10.0.0 0.0.255.255 area 0
    redistribute rip
Select the best response.
A. Redistributed routes will be tagged as external type 1 (E1) with a metric of 30.
B. Redistributed routes will be tagged as external type 2 (E2) with a metric of 20.
C. Redistributed routes will maintain their original RIP routing metric.
D. Redistributed routes will have a default metric of 0 and will be treated as unreachable and not
advertised.
E. Redistributed routes will have a default metric of 0 but will not be treated as reachable and will be
advertised.
Answer: B

请问答案肯定是B吗? 刚刚读另个题库, 这题答案居然是E.
---话说没有在redistribute 加上 subnets, 外部路由不是进不去吗?

rip宣告的是主类网段，不用加subnets也可以。

答案正确无误是B
后面不加subnets不是进不去，而是只重分发主类，弄清楚主类和子网的关系。。。不难理解
另外默认的度量值就是20
