Troubleshooting OSPFv3
The system provides several tools to troubleshoot OSPFv3 operation on the switch. This section describes typical, OSPFv3
troubleshooting scenarios.
NOTE: The following troubleshooting section is meant to be a comprehensive list, but only to provide some examples of
typical troubleshooting checks.
•
Have you enabled OSPF globally?
•
Is the OSPF process active on the interface?
•
Are the adjacencies established correctly?
•
Did you configure the interfaces for Layer 3 correctly?
•
Is the router in the correct area type?
•
Did you include the routes in the OSPF database?
•
Did you include the OSPF routes in the routing table (not just the OSPF database)?
Some useful troubleshooting commands are:
•
show ipv6 interfaces
•
show ipv6 protocols
•
debug ipv6 ospf events and/or packets
•
show ipv6 neighbors
•
show virtual links
•
show ipv6 routes
Viewing Summary Information
To get general route, configuration, links status, and debug information, use the following commands.
•
View the summary information of the IPv6 routes.
EXEC Privilege mode
show ipv6 route summary
•
View the summary information for the OSPFv3 database.
EXEC Privilege mode
show ipv6 ospf database
•
View the configuration of OSPFv3 neighbors.
EXEC Privilege mode
show ipv6 ospf neighbor
•
View debug messages for all OSPFv3 interfaces.
EXEC Privilege mode
debug ipv6 ospf [event | packet] {type slot/port[/subport]}
– For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port[/subport] information.
– For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
– For a port channel interface, enter the keywords port-channel then a number.
– For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
