图五　实验拓扑图及IP地址、DLCI分配

　　二、配置FrameRelay

以Router2为例，其它两个路由器相似，\\后是人为添加的注释，在实际配置时不存在

路由器配置完毕后，还需要配置Cloud0。

图六　根据路由器的相关配置，给Cloud0的serial0配置DLCI及LMI类型

图七　根据路由器的相关配置，给Cloud0的serial1配置DLCI及LMI类型

图八　根据路由器的相关配置，给Cloud0的serial2配置DLCI及LMI类型

图九　根据路由器的相关配置，配置Cloud0的FrameRelay

　　三、配置各个计算机，并使用ping命令校验网络的连通性
