Root-cause problems for OSPFNetwork lists the root-cause problems that are diagnosed for OSPFNetwork.
| Problem 1 |
Description |
|---|---|
| 1**Problems prevent neighbor relationships from forming on the affected interface(s). |
|
| AreaIDMismatch |
Area ID on at least one of the interfaces in this OSPF network does not match the area ID on the neighboring interfaces. |
| AreaTypeMismatch |
Area type on at least one of the interfaces in this OSPF network does not match the area type on the neighboring interfaces. |
| AuthKeyMismatch |
Authentication key on at least one of the interfaces in this OSPF network does not match the authentication key on the neighboring interfaces. |
| AuthTypeMismatch |
Authentication type on at least one of the interfaces in this OSPF network does not match the authentication type on the neighboring interfaces. |
| DuplicateRouterID |
At least two neighboring interfaces in this OSPF network have the same OSPF router ID. |
| HelloOrDeadIntervalMismatch |
Either the Hello interval on at least one of the interfaces in this OSPF network does not match the Hello interval on the neighboring interface, or the Dead interval on at least one of the interfaces in this OSPF network does not match the Dead interval on the neighboring interfaces. |
| MTUMismatch |
Maximum transmission unit (MTU) on at least one of the interfaces in this OSPF network does not match the MTU on the neighboring interfaces. |
| NetmaskMismatch |
Netmask on at least one of the interfaces in this OSPF network does not match the netmask on the neighboring interfaces. |
