华为/华三OSPF多区域配置

时间:2024-05-21 12:41:11

要实现ospf多区域通信,我们必须要知道ospf的两个特性:

1、骨干区域必须保持畅通  2、非骨干区域必须与骨干区域连接

组网方式:

华为/华三OSPF多区域配置

配置命令:

AR1:

[AR1]int loop 0 
[AR1-LoopBack0]ip ad 1.1.1.1 32
[AR1-LoopBack0]int g0/0/0
[AR1]ospf 1 router-id 1.1.1.1

AR3:

[AR3]int loop 0
[AR3-LoopBack0]ip ad 3.3.3.3 32
[AR3-LoopBack0]int g0/0/0
[AR3-GigabitEthernet0/0/0]ip ad 20.0.0.2 24
[AR3-GigabitEthernet0/0/0]int g0/0/1

AR4:

[AR4-LoopBack0]ip ad 4.4.4.4 32
[AR4-LoopBack0]int g0/0/0
[AR4-GigabitEthernet0/0/0]ip ad 30.0.0.2 24
[AR4]ospf 1 router-id 4.4.4.4
[AR4-ospf-1]area 2
[AR4-ospf-1-area-0.0.0.2]network 4.4.4.4 0.0.0.0
[AR4-ospf-1-area-0.0.0.2]network 30.0.0.0 0.0.0.255
 

如果你查看路由表存在全网的路由,那么我们的ospf就配置成功了,这个时候我们就可实现ospf全网通信了
