拓扑图

配置

开启LLDP功能，查看是否能通过QinQ隧道透传

sysname AR1
#
lldp enable 
#
interface GigabitEthernet0/0/0.10
 dot1q termination vid 10
 ip address 12.1.1.1 255.255.255.0 
 arp broadcast enable
#

sysname AR2
#
lldp enable 
#
interface GigabitEthernet0/0/0.10
 dot1q termination vid 10
 ip address 12.1.1.2 255.255.255.0 
 arp broadcast enable
#

开启二层协议透传LLDP，查看AR1与AR2是否能通过QinQ隧道发现对方（模拟器无法观察到现象）

sysname SW1
#
vlan batch 100
#
interface GigabitEthernet0/0/1
 port link-type dot1q-tunnel
 port default vlan 100
 l2protocol-tunnel lldp enable
#
interface GigabitEthernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
#

sysname SW2
#
vlan batch 100
#
interface GigabitEthernet0/0/1
 port link-type dot1q-tunnel
 port default vlan 100
 l2protocol-tunnel lldp enable
#
interface GigabitEthernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
#

结果查看

AR1 ping AR2，可以ping通

在SW2的G0/0/2口抓包，可看到两层VLAN tag
