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 not meant to be a comprehensive list, but only to provide 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 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} - event: View OSPF event messages. - packet: View OSPF packets. - For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port information (for example, passive-interface te 2/1). - For a port channel, enter the keywords port-channel then a number from 1 to 255. - For a 40-Gigabit Ethernet interface, enter the keyword FortyGigabitEthernet then the slot/port information (for example, passive-interface fo 2/3).
