20. Refer to the exhibit. Routers R1 and R2 are running EIGRP and have converged. On the basis of the
information that is presented, which statement is true?

A. All outgoing routing **s ** router R1 to router R2 will be suppressed, but the inbound **s will
continue to be received.
B. All incoming routing **s ** R2 will be suppressed, but the outgoing **s will continue to be sent.
C. Both outgoing and incoming routing **s on R1 will be stopped because of the passive-interface Serial0/0
configuration statement.
D. Both outgoing and incoming routing **s on R1 will be permitted because the distribute-list 20 out
Serial0/0 command cannot be used with association with the outgoing interface.
Answer: C
书上好像说passive-interface使接口进入被动状态，虽然不能发送更新，但是能接受。这里为什么选C？

像OSPF,EIGRP之类的routing protocol.这一种路由协议的特点是会与对方router建立关系,也就是说router之间会建neighbor,所以,一旦用了passive -interface之后,你就断开了router之间的关系．

因为no relationship, no **.因此,所有的**送不出去,介是也收不进来.

所以：Ｃ

RIP和IGRP.这一种routing protcol的特点是不会与对方router建立关系．所以,router是每隔一段时间就会发生只听不送的状况. 换句话说,只要routing protocol的process还在运行,routing **还是可以接收信息,只不过因为passive-interface指令的关系,**会送不出去,所以如果要阻止**送进 router中,还要加上distribute-list平当incoming **.

EIGRP 开启passive-interface后，双向都不能收发...
这个NA课程上貌似就已经讲过了吧...

像EIGRP和OSPF，需要通过hello包建立邻居关系，设置为被动接口后，无法保持邻居关系
