cisco帧中继实验

淡淡回忆

　　其中帧中继的设置：

　　其中设置端口的dlci号和名字（以后会用到，名字是随意设置的）
　　Serial 1 的设置也是这样但是dlci和名字不一样
　　其中第一个路由器的配置如下：

　　封装为帧中继并做静态地址映射，即手工设置的（其中的ip地址为自己本接口的地址 dlci号为对方的）
　　第二个路由器的设置：

https://www.iyunv.com/source/plugin/onexin_bigdata/file:///C:/Documents%20and%20Settings/Administrator/Local%20Settings/Temp/WindowsLiveWriter-429641856/supfiles255C35/clip_image012_thumb.jpg

　　这样两台路由器的设置就完成了
　　测试：
　　r1#show frame-relay map （查看映射表）
　　Serial2/0 (up): ip 192.168.1.2 dlci 100, static, broadcast, CISCO, status defined, active
　　此时可以互ping 对方了
　　这个实验用的是手工配置的静态地址映射
　　下面这个实验是利用IARP（反向地址解析）动态获得地址映射
　　还是如上的拓扑图和地址和dlci号。
　　首先先删除上面的配置：
　　r1(config-if)#no frame-relay map ip 192.168.1.2
　　r1(config-if)#frame-relay interface-dlci 100（ 指定本地的dlci号是多少）
　　r2(config-if)#no frame-relay map ip 192.168.1.1
　　r2(config-if)#frame-relay interface-dlci 200
　　r1#show frame-relay map
　　Serial2/0 (up): ip 192.168.1.2 dlci 100, dynamic, broadcast, CISCO, status defined, active
　　帧中继的子接口分为点到点子接口和多点子接口。点到点子接口有自己独立的dlci号和独立的网络地址，可以与其他物理接口或子接口建立虚电路连接（并且映射是动态映射）。多点子接口是用来与多个物理接口或多个子接口建立多个pvc的单个接都。所有参与的接口在同一个子网内。（映射是静态映射）
　　我们先做点到点子接口的实验吧
