• Have you enabled OSPF globally?
• Is the OSPF process active on the interface?
• Are adjacencies established correctly?
• Are the interfaces configured for Layer 3 correctly?
• Is the router in the correct area type?
• Have the routes been included in the OSPF database?
• Have the OSPF routes been included in the routing table (not just the OSPF database)?
Some useful troubleshooting commands are:
•
show interfaces
•
show protocols
•
debug IP OSPF events and/or packets
•
show neighbors
•
show routes
To help troubleshoot OSPFv2, use the following commands.
• View the summary of all OSPF process IDs enables on the router.

• View the LSAs currently in the queue.
EXEC Privilege mode
show ip ospf timers rate-limit
• View debug messages.
EXEC Privilege mode
debug ip ospf process-id [event | packet | spf | database-timers rate-limit]
To view debug messages for a specific OSPF process ID, use the
debug ip ospf process-id
command.
If you do not enter a process ID, the command applies to the first OSPF process.
To view debug messages for a specific operation, enter one of the optional keywords:
•
event
: view OSPF event messages.
•
packet
: view OSPF packet information.
•
spf
