H3C设备之静态缺省路由

 

 

 

使用默认缺省路由让PCA网络访问internet:

[RTA]interface S6/0

          ip address 192.168.1.1 24

          interface g0/0

          ip address 192.168.3.1

[RTB]interface S6/0

          ip address 192.168.1.2 24

          interface g0/0

          ip address 192.168.2.1 24

          ip route-static 192.168.3.0  255.255.255.0 192.168.1.1

PCA:192.168.3.2 255.255.255.0

PCB:192.168.2.2 255.255.255.0

现在如果PCA所在网段属于私网，想要访问公网PCB，此时可在RTA上做一条静态缺省路由：

[RTA]ip route-static 0.0.0.0 0.0.0.0 192.168.1.2      缺省路由使用0来匹配，因为不是点到点串口连接所以使用下一跳地址作为出口。

此时PCA能够访问internetPCB：
