CE1 GigabitEthernet1/0/0 VLANIF 10 10.1.1.1/24
CE2 GigabitEthernet1/0/0 VLANIF 10 10.1.1.2/24
Configuration Roadmap
The configuration roadmap is as follows:
1. Configure the routing protocol on the backbone network to implement interworking.
2. Set up a remote LDP session between the PEs.
3. Set up a tunnel between the PEs to transmit user data.
4. Enable MPLS L2VPN on the PEs.
5. Create VSIs on PEs, specify LDP as the signaling protocol, and bind the VSI to related AC
interfaces.
6. Configure QinQ sub-interfaces on the PE interfaces connected to the switches and connect
the QinQ sub-interfaces to the VPLS network.
7. Configure selective QinQ on the switch interfaces connected to CEs.
Data Preparation
To complete the configuration, you need the following data:
l VSI name and VSI ID
l IP addresses of peers and tunnel policy used for setting up the peer relationship
l Interfaces to which the VSI is bound
l Encapsulation mode of the sub-interfaces and VLANs that the sub-interfaces belong to
Procedure
Step 1 Configure the VLANs that the interfaces belong to according to Figure 5-12.
The configuration procedure is not mentioned.
NOTE
l The AC-side physical interface and PW-side physical interface of a PE cannot be added to the same
VLAN; otherwise, a loop occurs.
l After the configuration, the packets sent from a CE to a switch should contain a VLAN tag.
Step 2 Configure selective QinQ on the interfaces of the switches and specify the VLANs allowed by
the interfaces.
