帧中继Frame-Relay静态映射【实验名称】帧中继Frame-Relay静态映射【实验目的】 掌握利用静态映射方式实现Frame-relay连接。【背景描述】 你是某公司的网管，公司的网络运行在Frame-Relay上，分公司的设备不支持反转动态地址映射，本地端必须配置静态地址映射才能通讯，请你实现此操作。【实现功能】 地址映射手工配置，反映远端设备的IP地址和本地DLCI的对应关系。【实验拓扑】 【实验设备】 R2620或R2624路由器（4台）、m2602AS同异步接口模块一个、V35DCE（3根）、V35DTE（3根）【实验步骤】 第一步：基本配置，配置帧中继交换机Red-Giantenable Red-Giant(config)#hostname FRFR(config)#frame-relay switching !
