拓撲：

實現步驟：

1 先添加的交換機的vlan

[SW1]display this

sysname SW1

vlan batch 10 20

[SW2] vlan batch 10 20

2 進入交換機 接口配置接口所屬vlan：

[SW1：

interface Ethernet0/0/10

port link-type access

port default vlan 10

#

interface Ethernet0/0/20

port link-type access

port default vlan 20

SW2

interface Ethernet0/0/10

port link-type access

port default vlan 10

#

interface Ethernet0/0/20

port link-type access

port default vlan 20

#

配置交換機dot1Q. （trunk）

SW1：

#

interface Ethernet0/0/1

port link-type trunk

port trunk allow-pass vlan all

#

Sw2：#

interface Ethernet0/0/1

port link-type trunk

port trunk allow-pass vlan all

#

Sw3：

#

interface Ethernet0/0/10

port link-type trunk

port trunk allow-pass vlan 2 to 4094

##

interface Ethernet0/0/1

port link-type trunk

port trunk allow-pass vlan 2 to 4094

#

#

interface Ethernet0/0/2

port link-type trunk

port trunk allow-pass vlan 2 to 4094

#

查看 vlan信息

重點：單臂路由的配置：

[R1-Ethernet0/0/0.1]display this

#

interface Ethernet0/0/0.1

dot1q termination vid 10

ip address 192.168.1.1 255.255.255.0

arp broadcast enable

#

[R1-Ethernet0/0/0.2]display this

#

interface Ethernet0/0/0.2

dot1q termination vid 20

ip address 10.224.9.1 255.255.255.0

arp broadcast enable
