三路由器通过添加静态路由条目实现全网互通

第一步:分别先配置客户端和路由器的ip R1路由器的配置 <Huawei>system-view [Huawei-GigabitEthernet0/0/0]ip address 192.168.1.254 255.255.255.0 [Huawei-GigabitEthernet0/0/0]undo shutdown [Huawei-GigabitEthernet0/0/1]ip address 192.168.2.1 255.255.255.0 [Huawei-GigabitEthernet0/0/1]undo shutdown [Huawei-GigabitEthernet0/0/1]quit

R2路由器的配置 <Huawei>system-view [Huawei-GigabitEthernet0/0/1]ip address 192.168.2.2 255.255.255.0 [Huawei-GigabitEthernet0/0/1]undo shutdown [Huawei-GigabitEthernet0/0/2]ip address 192.168.3.2 255.255.255.0 [Huawei-GigabitEthernet0/0/2]undo shutdown [Huawei-GigabitEthernet0/0/2]quit

R3路由器的配置 <Huawei>system-view [Huawei-GigabitEthernet0/0/0]ip address 192.168.4.254 255.255.255.0 [Huawei-GigabitEthernet0/0/0]undo shutdown [Huawei-GigabitEthernet0/0/2]ip address 192.168.3.1 255.255.255.0 [Huawei-GigabitEthernet0/0/2]undo shutdown [Huawei-GigabitEthernet0/0/2]quit 第二步：添加静态路由条目 R1 添加静态路由条目 [Huawei]ip route-static 192.168.3.0 255.255.255.0 192.168.2.2 [Huawei]ip route-static 192.168.4.0 255.255.255.0 192.168.2.2

R2 添加静态路由条目 [Huawei]ip route-static 192.168.1.0 255.255.255.0 192.168.2.1 [Huawei]ip route-static 192.168.4.0 255.255.255.0 192.168.3.1

R3 添加静态路由条目 [Huawei]ip route-static 192.168.1.0 255.255.255.0 192.168.3.2 [Huawei]ip route-static 192.168.2.0 255.255.255.0 192.168.3.2

备注： 对R1,R3 也可以添加默认路由（缺省路由）条目 对R1 :[Huawei]ip route-static 0.0.0.0 0.0.0.0 192.168.2.2 对R3 :[Huawei]ip route-static 0.0.0.0 0.0.0.0 192.168.3.2
