1、实验拓扑
2、PC配置
3、将PC1和PC2划分为同一个vlan10,实现vlan10内的通信
（1）配置交换机SW1
[SW1]vlan batch 10 20
Info: This operation may take a few seconds. Please wait for a moment...done.
[SW1]interface e0/0/10
[SW1-Ethernet0/0/10]port link-type access
[SW1-Ethernet0/0/10]port default vlan 10
[SW1-Ethernet0/0/10]interface e0/0/11
[SW1-Ethernet0/0/11]port link-type access
[SW1-Ethernet0/0/11]port default vlan 10
[SW1-Ethernet0/0/11]interface e0/0/1
[SW1-Ethernet0/0/1]port link-type access
[SW1-Ethernet0/0/1]port default vlan 10
（2）测试PC1和PC2连通性
4、在R1上配置IP地址使得R1能与PC1和PC2通信
（1）路由器AR1配置
[AR1]interface g0/0/1
[AR1-GigabitEthernet0/0/1]ip add 192.168.10.254 24
5、实现AR3与PC3的通信
（1）交换机SW2配置
[SW2]vlan batch 10 20
Info: This operation may take a few seconds. Please wait for a moment...done.
[SW2]interface e0/0/1
[SW2-Ethernet0/0/1]port hybrid pvid vlan 20
[SW2-Ethernet0/0/1]port hybrid untagged vlan all
[SW2-Ethernet0/0/1]interface e0/0/10
[SW2-Ethernet0/0/10]port hybrid pvid vlan 20
[SW2-Ethernet0/0/10]port hybrid untagged vlan all
[SW2-Ethernet0/0/10]
（2）路由器AR3配置
[Huawei]sysname AR3
[AR3]interface g0/0/2
[AR3-GigabitEthernet0/0/2]ip add 192.168.3.254 24
6、静态路由
（1）在AR1,AR2,AR3配置IP地址
[AR1]interface g0/0/0
[AR1-GigabitEthernet0/0/0]ip add 12.12.12.1 24
[Huawei]sysname AR2
[AR2]interface g0/0/0
[AR2-GigabitEthernet0/0/0]ip add 12.12.12.2 24
[AR2-GigabitEthernet0/0/0]interface g0/0/1
[AR2-GigabitEthernet0/0/1]ip add 23.23.23.2 24
[AR3]interface g0/0/1
[AR3-GigabitEthernet0/0/1]ip add 23.23.23.3 24
（2）配置完IP后测试直连网段的通断
[AR1]ping 12.12.12.2

round-trip min/avg/max = 10/44/70 ms
（3）使用静态实现AR1到AR3的互通
（1） 配置AR1到AR3的静态路由
- [AR1]ip route-static 23.23.23.0 24 12.12.12.2
- （格式：ip route-static <目的网段或目的IP> <掩码> <下一跳IP地址或出接口号>） 使用tracert命令验证，AR1能通过AR2到达AR3，由于AR1和AR2是直连的，所以在到达AR2时返回数据，但之后就不通了。
[AR1]ip route-static 23.23.23.0 24 12.12.12.2
[AR1]tracert 23.23.23.3
traceroute to 23.23.23.3(23.23.23.3), max hops: 30 ,packet length: 40,press CT
RL_C to break
1 12.12.12.2 40 ms 50 ms 30 ms
2 * * *
3 * * *
4 * * *
5 * * * 原因：AR1有到达AR3的路由，但是AR3并不知道如何到达AR1
（2） 配置AR3到AR1的静态路由
- [AR3]ip route-static 12.12.12.0 24 23.23.23.2
[AR3]ip route-static 12.12.12.0 24 23.23.23.2
测试：
[AR1]ping 23.23.23.3

7、配置实现全网段的互通
（1）要求1：AR1能到达192.168.3.0/24网段
[AR1]ip route-static 192.168.3.0 24 12.12.12.2
[AR2]ip route-static 192.168.3.0 24 23.23.23.3
测试：
[AR1]tracert 192.168.3.3
traceroute to 192.168.3.3(192.168.3.3), max hops: 30 ,packet length: 40,press

3 192.168.3.3 110 ms 100 ms 110 ms
（2）要求2：AR3能到达192.168.12.0/24网段
[AR3]ip route-static 192.168.10.0 24 23.23.23.2
[AR2]ip route-static 192.168.10.0 24 12.12.12.1
测试：
[AR3]tracert 192.168.10.1
traceroute to 192.168.10.1(192.168.10.1), max hops: 30 ,packet length: 40,pres

2 12.12.12.1 60 ms 60 ms 70 ms
3 192.168.10.1 110 ms 100 ms 130 ms
8、在PC1或PC2上ping PC3观察是否实现全互通
