1) Use 

the 

display ip interface brief command to verify that the link layer works normally. 

2) Use 

the 

ping command to check network layer connectivity. 

3) Use 

the 

display ospf interface command to view the OSPF interface configuration. 

4)  If the network type of an interface is NBMA, use the display current-configuration configuration 

ospf command to verify that a neighbor is specified for the router. 

5) Use 

the 

display ospf brief command to check that the OSPF timers are consistent with those on 

the neighbor and that the dead time of the neighbor is four times the Hello interval. 

6) Use 

the 

display ospf peer command to view neighbors. 

The router running OSPF is unable to learn a complete network topology. 

Perform the following procedure to make analyses: 

1)  If multiple areas are configured on the router, check that one is specified as the backbone area. 

2)  Check that the backbone area is fully meshed. 

3)  Check that the backbone area is not configured as a Stub area or NSSA area. 

4)  Check that no virtual links are configured for the backbone area. 

5)  For a Stub area, check that the Stub attributes are configured for all routers in the area. 

6)  For an NSSA area, check that the NSSA attributes are configured for all routers in the area. 

7)  Check that Stub or NSSA areas are not a transit area of any virtual link. Virtual links cannot pass 

through a Stub or NSSA area. 

Perform the following procedure: 

1) Use 

the 

display ospf peer command to view the OSPF neighbor status. 

2) Use 

the 

display ospf interface command to view the OSPF configuration on an interface. 

3) Use 

the 

display ospf lsdb command to view the LSDB information. 

4) Use the display current-configuration configuration ospf command to view area 

configurations. 

5)  If a virtual link is configured, use the display ospf vlink command to check that the OSPF virtual 

link is normal.
