Troubleshoot OSPFv3
You can troubleshoot OSPFv3 operations and check questions for typical issues that interrupt a process.
• Is OSPFv3 enabled globally?
• Is OSPFv3 enabled on the interface?
• Are adjacencies established correctly?
• Are the interfaces congured for L3 correctly?
• Is the router in the correct area type?
• Are the OSPF routes included in the OSPF database?
• Are the OSPF routes included in the routing table in addition to the OSPF database?
• Are you able to ping the link-local IPv6 address of adjacent router interface?
