Troubleshoot OSPFv3
You can troubleshoot OSPFv3 operations, as well as check questions for any typical issues that interrupt a process.
● Is OSPFv3 enabled globally?
● Is OSPFv3 enabled on the interface?
● Are adjacencies established correctly?
● Are the interfaces configured 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?
