配置Frame-relay交换机.doc

配置Frame-relay交换机【实验名称】 Frame-relay交换机【实验目的】 掌握路由器作为帧中继交换机配置技术。【背景描述】 你是某网络技术培训公司的网管，为了提高学员的实际动手能力，公司决定为学员提供帧中继的环境，为了节省成本，要求你用一台至少有三个广域网同步接口的路由器模拟一个帧中继的环境。【实现功能】 用路由器模拟帧中继交换机，为实验模拟广域网帧中继接入。【实验拓扑】 【实验设备】 R2620或R2624路由器（4台）、m2603AS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Red-Giantenable Red-Giant(config)#hostname FRFR(config)#frame-relay switching !
