Configuration Roadmap
The configuration roadmap is as follows:
1. Run an IGP 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. Set up
MPLS LDP peer relations between U-PE1 and S-PE, and between U-PE2 and S-PE.
3. Create a PW template. Enable the CW and LSP ping function.
4. Configure the dynamic PW on the U-PE.
5. Create a switching PW on the switching node S-PE.
Data Preparation
To complete the configuration, you need the following data:
l L2VC IDs on U-PE1 and U-PE2 (the L2VC IDs should be different)
l MPLS LSR-IDs of U-PE1, S-PE, and U-PE2
l IP addresses of the remote peers
l Encapsulation type of the switching PW
l Name and parameters of the PW template on U-PEs
Procedure
Step 1 Configure interface addresses for CE, U-PE,P and S-PE according to Figure 6-14, including
VLAN and VLANIF interfaces.
The configuration procedure is not mentioned.
Step 2 Configure an IGP protocol on the MPLS backbone network.
Configure an IGP protocol on the MPLS backbone network. OSPF is used as the IGP protocol
in this example.
Configure interface addresses of the U-PE, S-PE, and P. 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.
After the configuration, run the display ip routing-table command on U-PE, P, or S-PE, and
you can see that the devices can learn each other's routes. Take the display on S-PE for example.
