•
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.
EXEC Privilege mode
show running-config ospf
•
View the summary information of the IP routes.
EXEC Privilege mode
show ip route summary
•
View the summary information for the OSPF database.
EXEC Privilege mode
show ip ospf database
•
View the configuration of OSPF neighbors connected to the local router.
EXEC Privilege mode
show ip ospf neighbor
•
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
: view SPF information.
•
database-timers rate-limit
: view the LSAs currently in the queue.
