After the configuration, the LDP neighbor relationship should be established between the PE
and the ASBR in the same AS. Running the display mpls ldp session command on the PE or
ASBR, you can find the session state is "Operational" in the output information.
Consider PE1 as an example.
[PE1] display mpls ldp session
LDP Session(s) in Public Network
Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
A '*' before a session means the session is being deleted.

TOTAL: 1 session(s) Found.
Step 3 Configure basic BGP/MPLS IP VPN on the MPLS backbone of AS 100 and AS 200 respectively.
NOTE
The VPN target of the VPN instances of the ASBR and the PE in the same AS should match. In different
ASs, the matching of the VPN target attributes of the PEs is unnecessary.
