3. Enable MPLS L2VPN and create VC connections on the PEs.
Data Preparation
To complete the configuration, you need the following data:
l IP address of the remote peer of each PE
l VC ID
Procedure
Step 1 Configure interface addresses for CE, PE and P according to Figure 5-7, including VLAN 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.
After the configuration, OSPF adjacencies are established between PE1, P, and PE2. By running
the display ospf peer command, you can see that the status of the OSPF adjacency is Full. Run
the display ip routing-table command, and you can see that the PEs can learn the routes of each
other's Loopback1 interface.
Step 3 Configure the basic MPLS capability and MPLS LDP on the MPLS network.
