实验12配置ospf

实验任务一：单区域ospf基本配置

1. 搭建实验环境
   

2. 在路由器上配置ip地址

3. 检查网络连通性和路由器路由表

4. 配置ospf
   [RTA]ospf 1 router-id 1.1.1.1
   [RTA-ospf-1]area 0
   [RTA-ospf-1-area-0.0.0.0]network 20.0.0.0 0.0.0.255
   [RTA-ospf-1-area-0.0.0.0]network 10.0.0.0 0.0.0.255
   [RTB]ospf 1 router-id 2.2.2.2
   [RTB-ospf-1]area 0
   [RTB-ospf-1-area-0.0.0.0]network 20.0.0.0 0.0.0.255
   [RTB-ospf-1-area-0.0.0.0]network 10.1.0.0 0.0.0.255
   5.检查路由器ospf邻居状态及路由表
   [RTA]display ospf peer
