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:
[PE1] display ip routing-table
