After you complete the configurations, the PEs and the ASBR-PEs in the same AS
should be able to set up LDP neighborhood. Executing the display mpls ldp session
command on the routers, you can find the Session State is "Operational" in the output.
You do not need to enable MPLS on the interface connecting ASBR-PE1 and
ASBR-PE2.
Take the display results on PE1 and ASBR-PE1 for example:
