VLAN间路由的实验：使用路由子接口(单臂路由)

使用交换机路由接口

1.场景说明

公司现有4个部门，每个部门有4个终端
有1台二层交换机，1台1P增强型的三层交换机
终端都连接在二层交换机上，每个部门规划一个VLAN
二层交换机上联三层交换机，三层交换机通过路由接口提供网关服务，并让所有终端之间可以互通

部门	网段	网关IP	VLAN号	VLAN名称描述
部门1	192.168.1.0/24	192.168.1.254	11	BuMen1
部门2	192.168.2.0/24	192.168.2.254	12	BuMen2
部门3	192.168.3.0/24	192.168.3.254	13	BuMen3
部门4	192.168.4.0/24	192.168.4.254	14	BuMen4

2.配置ASW

<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]sys ASW1
[ASW1]undo info-center enable
[ASW1]vlan batch 11 to 14
[ASW1]int g0/0/1
[ASW1-GigabitEthernet0/0/1]p l a
[ASW1-GigabitEthernet0/0/1]p d v 11
[ASW1-GigabitEthernet0/0/1]int g0/0/3
[ASW1-GigabitEthernet0/0/3]p l a
[ASW1-GigabitEthernet0/0/3]p d v 11
[ASW1-GigabitEthernet0/0/3]int g0/0/4
[ASW1-GigabitEthernet0/0/4]p l a
[ASW1-GigabitEthernet0/0/4]p d v 11
[ASW1-GigabitEthernet0/0/4]int g0/0/7
[ASW1-GigabitEthernet0/0/7]p l a 
[ASW1-GigabitEthernet0/0/7]p d v 12
[ASW1-GigabitEthernet0/0/7]int g0/0/9

[ASW1-GigabitEthernet0/0/10]p d v 12
[ASW1-GigabitEthernet0/0/10]int g0/0/13
[ASW1-GigabitEthernet0/0/13]p l a
[ASW1-GigabitEthernet0/0/13]p d v 13
[ASW1-GigabitEthernet0/0/13]int g0/0/15
[ASW1-GigabitEthernet0/0/15]p l a
[ASW1-GigabitEthernet0/0/15]p d v 13
[ASW1-GigabitEthernet0/0/15]int g0/0/16
[ASW1-GigabitEthernet0/0/16]p l a
[ASW1-GigabitEthernet0/0/16]p d v 13
[ASW1-GigabitEthernet0/0/16]int g0/0/19
[ASW1-GigabitEthernet0/0/19]p l a
[ASW1-GigabitEthernet0/0/19]p d v 14
[ASW1-GigabitEthernet0/0/19]int g0/0/21
[ASW1-GigabitEthernet0/0/21]p l a
[ASW1-GigabitEthernet0/0/21]p d v 14
[ASW1-GigabitEthernet0/0/21]int g0/0/22
[ASW1-GigabitEthernet0/0/22]p l a
[ASW1-GigabitEthernet0/0/22]p d v 14

3.配置CSW

<HUAWEI>sys
Enter system view, return user view with return command.
[~HUAWEI]sys CSW1
[*HUAWEI]comm
[~CSW1]int GE1/0/1
[~CSW1-GE1/0/1]undo portswitch
[*CSW1-GE1/0/1]ip addr 192.168.1.254 24
[~CSW1-GE1/0/1]undo shutdown

[*CSW1-GE1/0/1]int GE1/0/2
[*CSW1-GE1/0/2]undo portswitch 
[*CSW1-GE1/0/2]ip addr 192.168.2.254 24
[~CSW1-GE1/0/2]undo shutdown

[*CSW1-GE1/0/2]int GE1/0/3
[*CSW1-GE1/0/3]undo portswitch 
[*CSW1-GE1/0/3]ip addr 192.168.3.254 24
[~CSW1-GE1/0/3]undo shutdown

[*CSW1-GE1/0/3]int GE1/0/4	
[*CSW1-GE1/0/4]undo portswitch 
[*CSW1-GE1/0/4]ip addr 192.168.4.254 24
[~CSW1-GE1/0/4]undo shutdown

[*CSW1-GE1/0/4]quit
