Configuration Roadmap
The configuration roadmap is as follows:
1. Run a routing protocol on the devices of the backbone network to implement connectivity.
2. Configure the basic MPLS functions on the backbone network and set up an LSP.
3. Create an MPLS L2VC connection between the two U-PEs.
4. Create a switching PW on the S-PE.
Data Preparation
To complete the configuration, you need the following data:
l L2VC IDs of U-PE1 and U-PE2
l MPLS LSR-IDs of U-PE1, S-PE, and U-PE2
l Name of the PW template and attributes of the PW template used on the U-PEs
l VC labels of the PW (pay attention to the mapping between the VC labels on the two ends)
l Encapsulation type of the S-PE
Procedure
Step 1 Configure interface addresses for CE, U-PE,P and S-PE according to Figure 6-13, including
VLAN and VLANIF interfaces.
The configuration procedure is not mentioned.
Step 2 Configure an IGP protocol on the MPLS backbone network.
The OSPF protocol is used in this example.
Configure interface addresses of the U-PE, S-PE, and P according to Figure 6-13. When
configuring OSPF, note that the 32-bit loopback interfaces of U-PE1, S-PE, and U-PE2 must be
advertised.
The configuration procedure is not mentioned.
Step 3 Configure basic MPLS functions and set up tunnels.
Configure the basic MPLS capability on the MPLS backbone network. Set up LSPs between U-
PE1 and S-PE, and between S-PE and U-PE2. The configuration procedure is not mentioned.
Step 4 Create a VC connection.
Enable MPLS L2VPN on U-PE1 and U-PE2. Create VC connections on two U-PEs.
