1，组间通信：

2，设置：

（1）设置R2

设置eth0/0/1和ge0/0/0

<router2>system-view 
    Enter system view, return user view with Ctrl+Z.
    [router2]interface eth	
    [router2]interface Ethernet0/0/1
    [router2-Ethernet0/0/1]	
    [router2-Ethernet0/0/1]display this 
    #
    interface Ethernet0/0/1
     portswitch
     port link-type access
     port default vlan 10
    #
    return
    [router2-Ethernet0/0/1]q
    [router2]interface G	
    [router2]interface GigabitEthernet0/0/0
    [router2-GigabitEthernet0/0/0]display this
    #
    interface GigabitEthernet0/0/0
     portswitch
     port link-type access
     port default vlan 20
    #
    return
    [router2-GigabitEthernet0/0/0]

设置eth0/0/0

[router2]interface Ethernet0/0/0
    [router2-Ethernet0/0/0]display this
    #
    interface Ethernet0/0/0
     portswitch
     port link-type trunk
     port trunk allow-pass vlan 10 20
    #
    return
    [router2-Ethernet0/0/0]

（2）设置R3

设置eth0/0/1和ge0/0/0

<router3>system-view 
    Enter system view, return user view with Ctrl+Z.
    [router3]interface Ethe	
    [router3]interface Ethernet0/0/1
    [router3-Ethernet0/0/1]display this
    #
    interface Ethernet0/0/1
     portswitch
     port link-type access
     port default vlan 30
    #
    return
    [router3-Ethernet0/0/1]q	
    [router3]interface G	
    [router3]interface GigabitEthernet0/0/0
    [router3-GigabitEthernet0/0/0]display t	
    [router3-GigabitEthernet0/0/0]display this
    #
    interface GigabitEthernet0/0/0
     portswitch
     port link-type access
     port default vlan 40
    #
    return
    [router3-GigabitEthernet0/0/0]

设置eth0/0/0,允许vlan发送

[router3]interface Ethernet0/0/0
    [router3-Ethernet0/0/0]
    [router3-Ethernet0/0/0]display this
    #
    interface Ethernet0/0/0
     portswitch
     port link-type trunk
     port trunk allow-pass vlan 30 40
    #
    return
    [router3-Ethernet0/0/0]

（3）设置R1

设置eth0/0/0和设置eth0/0/1

[router1]interface Ethernet0/0/0
    [router1-Ethernet0/0/0]display this
    #
    interface Ethernet0/0/0
     portswitch
     port link-type trunk
     port trunk allow-pass vlan 10 20
    #
    return
    [router1-Ethernet0/0/0]q
    [router1]interface Ethernet0/0/1
    [router1-Ethernet0/0/1]display this
    #
    interface Ethernet0/0/1
     portswitch
     port link-type trunk
     port trunk allow-pass vlan 30 40
    #
    return

(4）配置ip:当二层设备需要与三层设备通信时，由于二层设备上都是二层口无法配置IP地址，所以可以创建基于VLAN的逻辑接口，即VLANIF接口。VLANIF接口是三层接口，可以配置IP地址，通过IP地址，该设备即能与三层其他设备互相通信。

interface Vlanif 10
    [PE-Vlanif10]ip address 10.110.5.3 24
    [PE-Vlanif10]quit
    [PE] interface Vlanif 20
    [PE-Vlanif20]ip address 10.110.6.3 24
    [PE-Vlanif20]quit
    [PE] interface Vlanif 30
    [PE-Vlanif30]ip address 10.110.4.3 24
    [PE-Vlanif30]quit
    [PE] interface Vlanif 40
    [PE-Vlanif40]ip address 10.110.3.3 24
