我的解答：
1.distribute-list在Reditribution中必须使用OUT（定义）.
2. 使用方法是 在 protocol process A 中通过定义好的prefix 来过滤 protocol B所分发过来的路由信息.
3. distribute-list block_net_1 out eigrp 1 就是在OSPF中 使用Block_net_1 来过滤来自于eigrp 1的网络路由
4. 与本题无关的另一个例子是distribute-list 1 out ospf 2,在eigrp xxx里告诉应用ACL 1 来过滤来自于ospf 2的网络路由

QUESTION 112
Refer to the exhibit. Router B is performing bidirectional redistribution between EIGRP and OSPF. The
network 10.100.1.0/24 should not be reachable from the 10.100.9.0/24 network. However, it needs to be
reachable from any network within the EIGRP domain. All other networks should be seen in both domains.
Which change to router B would accomplish these goals?
Select the best response.
A. Under the EIGRP process, insert the distribute-list block_net_1 out ospf 1 command.
B. Under the OSPF process, insert the distribute-list block_net_1 in serial1/0 command.
C. Under the EIGRP process, insert the distribute-list block_net_1 in serial1/0 command.
D. Under the OSPF process, insert the distribute-list block_net_1 out eigrp 1 command.
