其中幀中繼的設置：
其中設置端口的dlci號和名字（以後會用到，名字是隨意設置的）
Serial 1 的設置也是這樣但是dlci和名字不一樣
其中第一個路由器的配置如下：
封裝爲幀中繼並做靜態地址映射，即手工設置的（其中的ip地址爲自己本接口的地址 dlci號爲對方的）
第二個路由器的設置：
這樣兩臺路由器的設置就完成了
測試：
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
此時可以互ping 對方了
這個實驗用的是手工配置的靜態地址映射
下面這個實驗是利用IARP（反向地址解析）動態獲得地址映射
還是如上的拓撲圖和地址和dlci號。
首先先刪除上面的配置：
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號是多少）
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
幀中繼的子接口分爲點到點子接口和多點子接口。點到點子接口有自己獨立的dlci號和獨立的網絡地址，可以與其他物理接口或子接口建立虛電路連接（並且映射是動態映射）。多點子接口是用來與多個物理接口或多個子接口建立多個pvc的單個接都。所有參與的接口在同一個子網內。（映射是靜態映射）
我們先做點到點子接口的實驗吧
