After you complete the above configurations, OSPF adjacency should be established between PE 1, P,
and PE 2. Issuing the display ospf peer command, you can see that the adjacency status is Full.
Issuing the display ip routing-table command, you can see that the PEs have learned the loopback
route of each other. The following takes PE 1 as an example:
