Troubleshooting OSPFv2
Dell Networking OS has several tools to make troubleshooting easier.
Be sure to check the following, as these questions represent typical issues that interrupt an OSPFv2
process.
NOTE: The following is not a comprehensive list, just some examples of typical troubleshooting
checks.
• 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 virtual links
• 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
