华为单臂路由配置
拓扑：
实现步骤：
1 先添加的交换机的vlan
[SW1]display this
sysname SW1
vlan batch 10 20
[SW2] vlan batch 10 20
2 进入交换机 接口配置接口所属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
#
配置交换机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
重点：单臂路由的配置：
[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
最后 测试连通性：
