Troubleshoot OSPFv2

You can troubleshoot the OSPFv2 operations, and check questions for any typical issues that interrupt a process.

  • Is OSPF enabled globally?
  • Is OSPF 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 IPv4 address of adjacent router interface?
