After the configurations, P establishes an OSPF adjacency with PE 1 and PE 2 respectively. Issue the
display ospf peer 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. Take PE 1 as an example:
