Configuration Roadmap
The configuration roadmap is as follows:
1. Configure the routing protocol on devices on the backbone network (PE and P) to
implement interworking and enable MPLS.
2. Use the default tunnel policy to create an LSP and configure the LSP as the tunnel for data
transmission.
3. Enable MPLS L2VPN and create VC connections on the PEs.
4. Configure VLAN mapping of a single tag on the sub-interface of the PE1 interface
connected to CE1 and connect the sub-interface to the VLL.
5. Configure a dot1q sub-interface on the PE2 interface connected to CE2 and connect the
dot1q sub-interface to the VLL.
Data Preparation
To complete the configuration, you need the following data:
l Name of the remote peer of each PE
l VC ID
l VLAN IDs used in VLAN mapping
l Encapsulation mode of the sub-interfaces and VLANs that the sub-interfaces belong to
Procedure
Step 1 Specify the VLANs that the interfaces of CEs, PEs, and P belong to and set the IP addresses of
the corresponding VLANIF interfaces according to Figure 5-8.
After the configuration, the packets sent from a CE to a switch should contain a VLAN tag.
The configuration procedure is not mentioned.
