配置多区域的OSPF协议

在划分的三个区域和主区域中的每台路由器都开启OSPF进程，并指定接口所属区域网络拓扑图如下：首先配置路由器的接口IP地址：[R1]int g0/0/0[R1-GigabitEthernet0/0/0]ip add 12.0.0.1 8[R1-GigabitEthernet0/0/0]int g0/0/1[R1-GigabitEthernet0/0/1]ip add 13.0.0.1 8[R1-Gi

在划分的三个区域和主区域中的每台路由器都开启OSPF进程，并指定接口所属区域

网络拓扑图如下：
在这里插入图片描述
首先配置路由器的接口IP地址：

[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 12.0.0.1 8
[R1-GigabitEthernet0/0/0]int g0/0/1
[R1-GigabitEthernet0/0/1]ip add 13.0.0.1 8
[R1-GigabitEthernet0/0/1]quit
[R1]int LoopBack 0
[R1-LoopBack0]ip add 1.0.0.1 8
[R1-LoopBack0]quit
[R1-LoopBack1]ip add 172.16.0.1 24
[R1-LoopBack1]quit

R２、R３同理按照网络拓扑图配置

接着配置各个路由器接口的ｏｓｐｆ：

[R1]ospf
[R1-ospf-1]area 0
[R1-ospf-1-area-0.0.0.0]net 12.0.0.0 0.255.255.255
[R1-ospf-1-area-0.0.0.0]net 13.0.0.0 0.255.255.255
[R1-ospf-1-area-0.0.0.0]quit
[R1-ospf-1]area 1
[R1-ospf-1-area-0.0.0.1]net 172.16.0.1 0.0.0.0
[R1-ospf-1-area-0.0.0.1]net 1.0.0.1 0.0.0.0
[R1-ospf-1-area-0.0.0.1]quit

R２、R３同理按照网络拓扑图配置
查看配置好的ｏｓｐｆ接口：
