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 status is Full. 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:
