新实验四路由器的基本配置(静态路由、默认路由、RIP、ospf协议)

1、实验四配置路由器静态路由、默认路由和RIPv2、ospf协议一、实验目的RIPv2路由协议。本实验主要用来练习路由器的基本配置，包括静态路由、默认路由和二、配置静态路由和默认路由1.绘制拓扑图并保存，拓扑图如下图所示。连接说明：Router 2Router4路由器1型号为2516, 路由器2和路由器4的型号均为2501 ;路由器1的ethernet 0与路由器2的ethernet 0相连； 路由器1的serial 0与路由器4的serial 0相连；注意：在连接路由器 1和4的串口时，请选择路由器4作为DCE端；2、以路由器1、路由器2和路由器4为配置对象，进行相关设置。 按下表逐个设置路由器
