2、网络需求
a.在R2和R3相应的接口激活OSPF；R1不运行任何动态路由协议；
b. R2上配置去往192.168.1.0/24的静态路由；为了让OSPF域内的路由器能够通过OSPF学习到这条路由，在R2上将静态路由重发布到OSPF。
c.完成配置后要求PC1与PC2能够互访。
3、配置
给R1配置一条默认路由：
[R1] ip route-static 0.0.0.0 0.0.0.0 192.168.12.2
在R2的GE0/0/1口上激活OSPF：
[R2] ospf 1 router-id 2.2.2.2
[R2-ospf-1] area 0
[R2-ospf-1-area-0.0.0.0] network 192.168.23.0 0.0.0.255
[R2-ospf-1-area-0.0.0.0] quit
[R2-ospf-1] quit
在R2上将静态路由重发布到OSPF。
[R2] ospf 1
[R2-ospf-1] import-route static
在R3的GE0/0/0及GE0/0/1口上激活OSPF：
[R3] ospf 1 router-id 3.3.3.3
[R3-ospf-1] area 0
[R3-ospf-1-area-0.0.0.0] network 192.168.23.0 0.0.0.255
[R3-ospf-1-area-0.0.0.0] network 192.168.2.0 0.0.0.255
