After the configuration, the OSPF neighbor relation can be established between the ASBR and
the PE in the same AS. Run the display ospf peer command, and you can find that the neighbor
status is Full.
The ASBR-PE and PE in the same AS can ping each other and learn the loopback interface
address of each other.
Step 3 Configure the basic MPLS function and MPLS LDP on the MPLS backbone networks of AS
100 and AS 200 and set up the MPLS LDP LSP.
# Configure the basic MPLS function on PE1 and enable LDP on the interface connected to
ASBR-PE1.
