26.5.6 OSPF Troubleshooting
The OSPF protocol may not be working properly due to errors such as physic connection,
configuration error when configuring and using the OSPF protocol. So users should pay
attention to following:
 First ensure the physic connection is correct
 Second, ensure the interface and link protocol are UP (use show interface command)
 Configure different IP address from different segment on each interface
 Then initiate OSPF protocol (use router-ospf command) and configure the OSPF area
on corresponding interface
After that, a OSPF protocol feature should be checked---the OSPF backbone area should be
continuous and apply virtual link to ensure it is continuous. if not; all non 0 areas should only
be connected to other non 0 area through 0 area; a border Layer 3 switch means that one part
of the interfaces of this switch belongs to 0 area, the other part belongs to non 0 area; Layer 3
switch DR should be specified for multi-access network such as broadcast network.
