Troubleshooting OSPFv3The system provides several tools to troubleshoot OSPFv3 operation on the switch. This section describes typical, OSPFv3troubleshooting scenarios.NOTE: The following troubleshooting section is meant to be a comprehensive list, but only to provide some examples oftypical 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 routesViewing Summary InformationTo get general route, configuration, links status, and debug information, use the following commands.• View the summary information of the IPv6 routes.EXEC Privilege modeshow ipv6 route summary• View the summary information for the OSPFv3 database.EXEC Privilege modeshow ipv6 ospf database• View the configuration of OSPFv3 neighbors.EXEC Privilege modeshow ipv6 ospf neighbor• View debug messages for all OSPFv3 interfaces.EXEC Privilege modedebug 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.Open Shortest Path First (OSPFv2 and OSPFv3) 611
