After the configuration, the OSPF neighbor relationship should be established between PE1 and
the P and between the P and PE2. After running the display ospf peer command, you can find
that the OSPF neighbor relationship is in Full state. Run the display ip routing-table command
on the PEs, and you can find that the PEs have learned the routes of the Loopback1 interface of
each other.
Use PE1 as an example:
[PE1] display ip routing-table
