After the configurations, OSPF adjacencies are established between PE 1, P, and PE 2. Execute the
display ospf peer command. The output shows that the adjacency is in the Full state. Execute the
display ip routing-table command. The output shows that the PEs have learned the routes to the
loopback interfaces of each other. Take PE 1 as an example:

2. Configure basic MPLS and enable MPLS LDP on the MPLS backbone to establish LDP LSPs:
