ip静态路由

网络拓扑图

基础

命令的格式一般是ip route-static 目的网络 掩码 网关 preference 优先级 。

报文传递流程:

R1路由端口ip配置

为GigabitEthernet0/0/0 端口配置ip:192.168.1.1

为GigabitEthernet0/0/1 端口配置ip:192.168.4.1

interface GigabitEthernet0/0/0
ip address 192.168.1.1 255.255.255.0
interface GigabitEthernet0/0/1
ip address 192.168.4.1 255.255.255.0

R1路由静态ip配置

ip route-static 192.168.2.0 255.255.255.0 192.168.4.2
ip route-static 192.168.3.0 255.255.255.0 192.168.4.2

解释：ip route-static 目的网段 子网掩码 下一跳地址

（我的理解就是 如果你要去找192.168.2.2这个ip，我应该发信息发送给192.168.4.2。而192.168.4.2这个ip就是路由R2 与R1路由相连端口的ip）

详细配置

sys后直接复制粘贴改代码就好了

R1路由的配置

interface GigabitEthernet0/0/0
 ip address 192.168.1.1 255.255.255.0
 quit
interface GigabitEthernet0/0/1
 ip address 192.168.4.1 255.255.255.0
quit
ip route-static 192.168.2.0 255.255.255.0 192.168.4.2
ip route-static 192.168.3.0 255.255.255.0 192.168.4.2

R2路由的配置

interface GigabitEthernet0/0/0
ip address 192.168.4.2 255.255.255.0
quit
interface GigabitEthernet0/0/1
ip address 192.168.6.1 255.255.255.0
quit
interface GigabitEthernet0/0/2
ip address 192.168.5.1 255.255.255.0

quit

ip route-static 192.168.1.0 255.255.255.0 192.168.4.1
ip route-static 192.168.2.0 255.255.255.0 192.168.6.2
ip route-static 192.168.3.0 255.255.255.0 192.168.5.2

R4路由

interface GigabitEthernet0/0/1
ip address 192.168.5.2 255.255.255.0
quit
interface GigabitEthernet0/0/2
ip address 192.168.3.1 255.255.255.0

ip route-static 192.168.1.0 255.255.255.0 192.168.5.1
ip route-static 192.168.2.0 255.255.255.0 192.168.5.1
