Example for Configuring QinQ-based VLAN Tag Swapping for VPLS Access
After QinQ-based VLAN tag swapping is configured on an interface, the interface swaps the inner and outer virtual local area network (VLAN) tags carried in double-tagged packets when receiving them. This configuration does not take effect on single-tagged packets.
Networking Requirements
On the network shown in Figure 1, customers 1 to 1000 have three types of services: unicast high-speed Internet (HSI) services, unicast Voice over Internet Protocol (VoIP) services, and multicast Internet Protocol television (IPTV) services.
When customers 1 to 1000 send both unicast and multicast services, CE1 and CE2 add to packets inner VLAN tags indicating the services, and the CE3 adds to packets outer VLAN tags indicating the users. QinQ-based VLAN tag swapping needs to be configured on the user-end provider edge (UPE) to swap the inner and outer VLAN tags in double-tagged packets. As such, the outer tags in the packets indicate the services, and the inner tags indicate the users.
QinQ VLAN tag termination sub-interfaces are created on the UPE based on double VLAN tags in packets from the CE3, and the UPE provides virtual private LAN service (VPLS) access to services through these sub-interfaces.
Provide VPLS access for unicast services.
Create subinterface 1 on the UPE to provide VPLS access for HSI and VoIP services (in service VLAN 7) and configure subinterface 1 as a QinQ VLAN tag termination sub-interface in symmetrical mode to terminate the outer VLAN tags of packets. The inner VLAN tags of packets are transparently transmitted to the provider edge-access aggregation gateway (PE-AGG).
Configure subinterface 1 on the PE-AGG as a QinQ VLAN tag termination sub-interface in symmetrical mode. After receiving packets from the UPE, subinterface 1 adds a VLAN tag to each packet and forwards the packets to the Service point of presence (POP).
Provide VPLS access for multicast services.
Create subinterface 2 on the UPE to provide VPLS access for IPTV services (in service VLAN 8) and configure subinterface 2 as a QinQ VLAN tag termination sub-interface in asymmetrical mode to terminate the inner and outer VLAN tags of packets.
Configure subinterface 2 on the PE-AGG as a QinQ VLAN tag termination sub-interface in asymmetrical mode. After receiving packets from the UPE, subinterface 2 adds the service VLAN 8 to the packets and forwards the packets to the Service POP.
Configuration Roadmap
The configuration roadmap is as follows:
- Configure QinQ on the CE3 so that each packet received by the UPE carries two VLAN tags.
- Configure an Interior Gateway Protocol (IGP) on the Multiprotocol Label Switching (MPLS) backbone network.
- Enable basic MPLS functions and Label Distribution Protocol (LDP) on the MPLS backbone network.
- Enable MPLS Layer 2 virtual private network (L2VPN).
- Create virtual switching instances (VSIs) and specify LDP as the signaling protocol of the VSIs.
- Configure VLAN tag swapping and QinQ VLAN tag termination sub-interfaces, and bind the AC interfaces to the VSIs.
- Enable Internet Group Management Protocol (IGMP) snooping and configure the static router interface and querier.
Data Preparation
To complete the configuration, you need the following data:
IDs of inner VLAN tags that CE1 and CE2 add to packets to distinguish services
IDs of outer VLAN tags that the CE3 adds to packets to distinguish users
IP address of each interface
VSI ID (which is the same on the UPE and PE-AGG)
MPLS LSR IDs on the UPE and PE-AGG
VSI names on the UPE and PE-AGG
Names of interfaces bound to the VSIs
Procedure
- Configure QinQ so that the CE3 sends double-tagged packets to the UPE.
Switch Layer 3 interfaces to Layer 2 interfaces.
If the interface is a Layer 2 interface, skip this step.
