新版BSCI实验手册-配置ospf验证,汇总,虚链路

1、新版BSCI 实验手册-配置ospf 验证，汇总，虚链路 环境：三台路由器串口相连，其它接口配置如图要求：1. 在area 1配置ospf 虚链路,router-id 如图配置2. 将R1的LOOP 口配置ospf 手工路由汇总3.配置ospf 接口验证（R1 和R2）4. 使用show 命令查看结果 步骤一： 配置三个路由器接口使其连通。R1的配置R1(config# interface Loopback0R1(config-if# ip address 30.1.1.1 255.255.255.0R1(config# interface Loopback1R1(config-if# ip
