Configuration example for QinQ termination supporting PPPoE server
Network requirements
As shown in Figure 24:
QinQ is enabled on GigabitEthernet 2/1/2 of Layer 2 Switch B.
The router acts as a PPPoE server. Hosts in different VLANs access the Internet through the PPPoE server.
Configure QinQ termination, so that the hosts can access the Internet.
