路由器要使用二层接口才能互联互通（e0/0/0），三层接口不能连通。
配置如下：
[sw1]dis cu
vlan batch 2 to 3 10
vlan 10
mux-vlan
subordinate separate 3
subordinate group 2
interface GigabitEthernet0/0/1
port link-type access
port default vlan 2
port mux-vlan enable
interface GigabitEthernet0/0/2
port link-type access
port default vlan 2
port mux-vlan enable
interface GigabitEthernet0/0/3
port link-type access
port default vlan 3
port mux-vlan enable
interface GigabitEthernet0/0/4
port link-type access
port default vlan 3
port mux-vlan enable
interface GigabitEthernet0/0/5
port link-type access
port default vlan 10
port mux-vlan enable
return
[r1]dis cu
[V200R003C00]
vlan batch 10
interface Vlanif10
ip address 1.1.1.254 255.0.0.0
interface Ethernet0/0/0
port link-type access
port default vlan 10
return
聚合vlan，此时SW2是终端的网关。
配置如下：
[sw2]dis cu
sysname sw2
vlan batch 2 to 3 10
vlan 10
aggregate-vlan
access-vlan 2 to 3
interface Vlanif10
ip address 1.1.1.254 255.0.0.0
interface GigabitEthernet0/0/1
port link-type access
port default vlan 2
interface GigabitEthernet0/0/2
port link-type access
port default vlan 3
return
