After you complete the configurations, each PE and the ASBR PE in the same AS can establish

neighbor relationship. Issue the display mpls ldp session command on the devices. The output
shows that the session status is Operational.

Configure VPN instances on PEs to allow CEs to access the network

NOTE:

For the same VPN, the VPN targets for the VPN instance on the PE must match those for the VPN instance
on the ASBR-PE in the same AS. This is not required for PEs in different ASs.
