l VLANs for the Internet access service of different users: VLAN 1000 to VLAN 1100
l Shared VLAN for the IPTV service: VLAN 1101
l Shared VLAN for the VoIP service: VLAN 1102
l Shared VLAN for home gateways: VLAN 1103
Each community switch is connected to 50 downstream corridor switches and maps the VLAN
IDs in the packets of the Internet access service from the corridor switches to VLAN 101 to
VLAN 150.
The aggregate switch of the carrier is connected to 50 downstream community switches and
adds outer VLAN IDs 21 to 70 to the packets sent from the community switches.
After user devices are powered on, they send service request packets to the switch of the carrier.
After the user devices pass the authentication, services can be used.

Configuration Roadmap
The configuration roadmap is as follows:
1. Create VLANs on SwitchA and SwitchB.
2. Configure VLAN mapping on SwitchB and add GE 1/0/0 and GE 2/0/0 to the VLANs.
3. Configure selective QinQ on SwitchA and add GE 1/0/0 to VLANs.
4. Add other downlink interfaces of SwitchA and SwitchB to the VLANs. The configurations
are similar to the configurations of their GE 1/0/0 interfaces.
