静态路由实验

路由器划分成3个广播域，如图

192.168.1.0/24
192.168.2.0/24
192.168.3.0/24
1.PC必须配置网关地址：网关地址是网段中连接其他网段的路由器的接口上的接口地址
2.AR1配置：
[Huawei]sysname AR1
[AR1]int g0/0/0
[AR1-GigabitEthernet0/0/0]ip address 192.168.1.254 24
[AR1-GigabitEthernet0/0/0]int g0/0/1
[AR1-GigabitEthernet0/0/1]ip address 192.168.2.1 24
3. AR2配置
sys
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname AR2
[AR2]int g0/0/0
[AR2-GigabitEthernet0/0/0]ip address 192.168.2.2 24
Mar 15 2025 22:21:22-08:00 AR2 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP
on the interface GigabitEthernet0/0/0 has entered the UP state.
[AR2-GigabitEthernet0/0/0]int g0/0/1
[AR2-GigabitEthernet0/0/1]ip address 192.168.3.254 24
Mar 15 2025 22:21:54-08:00 AR2 %%01IFNET/4/LINK_STATE(l)[1]:The line protocol IP
on the interface GigabitEthernet0/0/1 has entered the UP state.
4. 查询路由表；此时R1中不包含R2信息；R2不包含R1地址信息
[AR1]display ip routing-table
5.配置静态路由：
目标网段 掩码 下一跳IP
[AR2]ip route-static 192.168.1.0 24 192.168.2.1
sys
Enter system view, return user view with Ctrl+Z.
[AR1]ip route-static 192.168.3.0 24 192.168.2.2

display IP routing-table
5. PC1可以ping通PC2了

浅浅总结一波：
PC配置IP地址，
router配置接口IP
分别配置静态路由，R1对192.168.3.0/24网段
R2对192.168.1.0/24网段
因为跨路由器了，不是直连，direct路由表中没有，如果不加，路由器不知道向哪里转发，所以消息无法到达
