# Configure the Hub-PE.
[Hub-PE] mpls lsr-id 2.2.2.9
[Hub-PE] mpls
[Hub-PE-mpls] label advertise non-null
[Hub-PE-mpls] quit
[Hub-PE] mpls ldp
[Hub-PE-mpls-ldp] quit
[Hub-PE] interface vlanif 10
[Hub-PE-Vlanif10] mpls
[Hub-PE-Vlanif10] mpls ldp
[Hub-PE-Vlanif10] quit
[Hub-PE] interface vlanif 20
[Hub-PE-Vlanif20] mpls
[Hub-PE-Vlanif20] mpls ldp
[Hub-PE-Vlanif20] quit
After the configuration, LDP peer relation can be set up between the Hub-PE and the Spoke-
PEs. Run the display mpls ldp session command on each S9300, and you can see that the session
status is Operational.
The configuration procedure of the Spoke-PE is similar to the configuration procedure of the
Hub-PE and is not mentioned here.
Step 3 Configure VPN instances on each PE and connect the CEs to the PEs.

Issue 01 (2009-07-28)
NOTE
The Hub-PE and Spoke-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.
NOTE
The VPN targets of the two VPNs on the Hub-PE are advertised by the two Spoke-PE, and the advertised
VPN target is different from the received VPN target. The import VPN target on the Spoke-PE is the export
VPN target on the Hub-PE.
