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
