在cisco路由器上,用侦中继封装配置一个接口,inverse arp缺省是打开的.如果你对指定的dlci配置静态映射,inverse arp对这个dlci是自动关闭的.如果在这一端的路由器根本不支持inverse arp,也不支持你希望在侦中继上使用的特定协议的inverse arp,就必须用静态映射.]

接入端口在指定端口选举中不扮演任何角色。中继端口是用来连接到其他交换机的。接入端口是用来连接到主机或路由器的。这里所描述 的过程涉及的STP参数都是在中继链路上交互的。

[b]实验:RIP工作原理监视[/b]
[b]实验目的:监视RIP的工作原理[/b]
[b]由于想知道rip的工作原理,所以决定利用手册一1.7的实验做个扩展来监视一下RIP的工作原理..[/b]
[b]拓扑[/b]
[b]----------(r2)(s2/0)-------(s1/0)(r1)(s2/0)---------(s1/0)(r 3)-----------\[/b]
[b]整个工作过程如下:[/b]
[b]1)我在路由器的每个接口上都配了IP,从中间的路由器上都能ping通它的对端;[/b]
[b]2)在每个路由器上都开了debug ip rip ,用于监视rip的输出;[/b]
[b]3)在每个路由器上敲入router rip,然后观察每个路由器的debug输出,大概等了5分钟没有debug输出,我们
可以得出结论,虽然是起用了rip,但是还没有把它应用到接口是不能起作用;[/b]
[b]4)我在r1上输入net 148.1.0.0 ,debug输出如下;[/b]
[b]*Jul 29 12:25:01.759: RIP: sending request on Serial1/0 to 255.255.255.255

[b]从中可以发现一些现象,我来分析一下,它只从启用的接口上发出请求和一条空的更新,并观察到每更新一次时间大约是28s.同时注 意到r2上也没有什么动作.(原因r2上还没有在对应的接口上启用rip) [/b]
[b]5)我在r1上输入net 192.1.1.0 ,debug输出如下;[/b]

[b]可以看到它只是发送了一次request,以后就是每个28s发送一下路由更新,路由有水平分割的作用,只向一个方向发送.其它 路由也没有动作.[/b]

[b]注意到从接口上学的到路由条目就没有从接口上传出去,解释一下,我从s1/0上学到了3条[/b]
[b]分别是 2.0.0.0 148.1.0.0 152.1.0.0 就没有从s1/0在传出去,相同的原因1.0.0.0也[/b]
[b]是一样的道理,我在s1/0上启用了水平分割后呢?我看看效果吧![/b]
