After the configuration, OSPF adjacencies are established between Spoke-PE 1 and Hub-PE, and
between Spoke-PE 2 and Hub-PE. 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 Spoke-PE 1 as an example:
[Spoke-PE1] display ip routing-table
