Data Preparation
To complete the configuration, you need the following data:
l IDs of the VLANs that the interfaces of PE and CE belong to, as shown in Figure 3-8
l IP address of each VLAN interface, as shown in Figure 3-8
l MPLS LSR-IDs of UPE, SPE, and PE
l VPN instances on UPE, SPE, and PE
Procedure
Step 1 Configure OSPF on the MPLS backbone network to implement network connectivity.
After the configuration, an OSPF adjacency is set up among UPE, SPE, and PE. Run the display
ospf peer command, and you can see that the adjacency is in Full state. Run the display ip
routing-table command on the PEs, and you can see the PEs can learn the loopback routes of
each other.
The configuration procedure is not mentioned.
Step 2 Configure basic MPLS functions and MPLS LDP on the MPLS backbone network and set up
LDP LSPs.
NOTE
The PE devices are directly connected In this example, you need to run label advertise command to enables
the egress node to assign labels normally to the penultimate hop.
After the configuration, LDP sessions are established between UPE and SPE, and between SPE
and PE. By running the display mpls ldp session command, you can see that the session status
is Operational. By running the display mpls ldp lsp command, you can see the establishment
status of the LDP LSP.
The configuration procedure is not mentioned.
Step 3 Connect PEs to CEs and run BGP between them.
