Configuration Roadmap
The configuration roadmap is as follows:
1. Enable MPLS and MPLS L2VPN.
2. Create a static L2VC connection between PEs and manually configure the VC label.
Data Preparation
To complete the configuration, you need the following data:
l Labels of the static L2VC connection
The out-label of PE1 is the same as the in-label of PE2; whereas the in-label of PE1 is the same
as the out-label of PE2.
Procedure
Step 1 Configure interface addresses for CE, PE and P according to Figure 5-6, including VLAN
interfaces and VLANIF interfaces.
The configuration procedure is not mentioned.
Step 2 Configure IGP on the MPLS backbone network. (In this example, OSPF is used.)
When configuring OSPF, advertise the 32-bit addresses of loopback interfaces on PEs and P.
The loopback interface addresses are the LSR IDs.
The configuration procedure is not mentioned.
Step 3 Configure basic MPLS functions and LDP on the MPLS backbone network. That is, set up LDP
LSPs.
