1、图三图四把路由器2811的串口与云的串口相连，路由器的串口为DTE图五实验拓扑图及IP地址、DLCI分配二、配置Frame Relay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Routeren进入特权配置模式Router#conf t进入全局配置模式Enter configuration commands, one per line. End with CNTL/Z.Router（config）#no ip domain-lookup取消名称解析Router（config）#hostname Router2配置路由器的名字Router2（config）#i
