关于RIP协议当中的Passive interface的理解？

ccnafasttrack

现在我们拓扑当中的R6和R7所有接口都宣告进RIPV2当中，且关闭自动汇总。在R6和R7的S2/0接口上都启用触发更新ip rip triggered，且将R6的S2/0置为Passive-interface。
按照我之前的理论，如果rip协议当中，将宣告进RIP进程的接口置为被动接口，这个接口不会发送任何RIP更新，但是它会接收其他路由器发送的RIP更新，但是我现在在R6上并没有看到R7上的环回口路由，请问这是怎么回事？
我记得之前在听CCNA课程的时候，有老师提过，说如果在RIP上开启了触发更新，也就意味着要建立类似于EIGRP和OSPF的邻居关系，是不是现在给R6的S2/0接口配置了被动接口，关于RIP R6什么都发不出去了，也就建立不了邻居，所以R7的环回口路由就过不来了？
--------------------------------------------------------------------------------------------
补充说明：我又稍微等了一会，发现R7的环回口路由过来了，就是要慢很多，这是怎么回事？另外我上述描述是否正确？
求救！！！！！！！！！！！

我理解的是，开了触发更新以后，如果拓扑发生改变，路由器就会发送一条通告，告知失效的路由条目不能用了。条目进入抑制。而沉默端口则是只监听，不发送。r6起了沉默端口，但是能监听到r7发送的条目啊，就是得等到更新计时器超时。你的情况应该是查看的时候更新计时器未超时，r7没有发送更新报文。
