帧中继(用网云)的配置
一、对几台路由器进行模块的添加,对pc机进行ip的配置。
同时对路由器进行模块的添加,我已习惯了了用模块0,常用的端口都是s0/0/0,同时我用的是2811的路由器。
其拓扑图为:

二、对几台路由器进行配置(基本的配置和帧中继的配置)
这里我就以R1为例,因为R2、R3是类似的。

R1(config-subif)#frame-relay interface-dlci 102
R1(config-subif)#ex
R1(config)#int s0/0/0.2 point-to-point
R1(config-subif)#ip add 192.168.2.1 255.255.255.0
R1(config-subif)#frame-relay interface-dlci 103
R1(config-subif)#ex
R1(config)#router rip
R1(config-router)#net 192.168.10.1
R1(config-router)#net 192.168.1.1
R1(config-router)#net 192.168.2.1
R1(config-router)#^Z
注意:R2、R3进行同样的配置,但是要注意的是其对应性:即R1的102和R2的201在同一个网段,R1的103和R3的301在同一个网段,R2的203和R3的302在同一个网段。之所以要配置rip协议,其目的是为了整个网络的连通性。当然其他的像ospf协议也可以。
三、对中间的网继云进行配置

这里我们要注意那个对应性,即frame relay 模块的的对应性,换个说法就是要保证网络的畅通(有去有回)。
四、查看网络是否真的连通,即使用ping命令进行查看
由此可见,网络的连通性是很好的,实验室成功的,网络是可以通信的,至于要追求更高的安全性什么的就得再使用其他的协议以及其他的设备。
