5. Verification and testing: (1) View the information of adjacency and routing table
(2) Test:
6. Summary: configuration ideas:
(1) configure the physical interface IP addresses of four routers
(2) configure the loopback IP address interface loopback 0 of each router
(3) R2 creates ospf backbone area area 0, R3 R4 creates non-backbone area area 1, and declares precise ospf links (physical IP and loopback IP addresses)
(4) R2 creates backbone area 0 and non-backbone area 1 and accurately declares the address
(5) the ping command verifies whether the network is interconnected.
