实验拓扑
实验需求
实验步骤
每台路由器都要将本地的所有直连网段宣告至 OSPF 区域下
IP 地址配置
AR1 配置
[AR1-GigabitEthernet0/0/1]ip address 10.0.1.1 24
[AR1-GigabitEthernet0/0/0]ip address 192.168.1.1 24
[AR1-LoopBack0]ip address 1.1.1.1 32
AR2配置
[AR2-GigabitEthernet0/0/0]ip address 192.168.1.2 24
[AR2-GigabitEthernet0/0/1]ip address 192.168.2.1 24
[Huawei-LoopBack0]ip address 2.2.2.2 32
AR3配置
[Huawei-GigabitEthernet0/0/0]ip address 192.168.2.2 24
[Huawei-GigabitEthernet0/0/1]ip address 20.0.1.1 24
[AR3-LoopBack0]ip address 3.3.3.3 32
配置好主机 IP地址及网关
