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 Switch, 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.

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.
