After the configuration, OSPF relations are established between PE1, P, and PE2. By running
the display ospf peer command, you can see that the status of the OSPF relations is Full. By
running the display ip routing-table command, you can see that the PEs can learn the routes
of Loopback1 interface of each other.
Take the display on PE1 as an example.
