After you complete 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:
