Configure the router:
# Create Ethernet subinterface GigabitEthernet 1/0/1.10, and assign an IP address to the
subinterface.

[Router] interface gigabitethernet 1/0/1.10
[Router-GigabitEthernet1/0/1.10] ip address 1.1.1.11 255.255.255.0
# Enable QinQ termination on GigabitEthernet 1/0/1.10 to terminate the VLAN-tagged packets
with the Layer 1 VLAN ID 100 and the Layer 2 VLAN ID 11.

Verifying the configuration
# Verify that Host A and Host B can ping each other. (Details not shown.)
Ambiguous QinQ termination configuration example
Network requirements
As shown in
, QinQ is enabled on GigabitEthernet 1/0/2 of Layer 2 Switch B.
Configure ambiguous QinQ termination, so that hosts can communicate with the server group.
