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