OSPF/4/OSPF_IF_CONFIG_ERROR

Message

OSPF/4/OSPF_IF_CONFIG_ERROR: A packet is received on the non-virtual interface from a router whose configuration conflicts with the local configuration. (RouterId=[RouterId], IfIpAddress=[IfIpAddress], AddressLessIf=[AddressLessIf], PacketSrc=[PacketSrc], ConfigErrorType=[ConfigErrorType], PacketType=[PacketType], ProcessId=[ProcessId], AreaId=[AreaId])

Description

The configurations on the two interfaces for establishing an OSPF neighbor relationship were inconsistent with each other. The possible cause is that the hello, dead, or poll timer on one end was inconsistent with that on the peer end, or the interfaces were not configured on one area.

Parameters

Parameter Name	Parameter Meaning
RouterId	Router ID of the local device
IfIpAddress	IP address of the non-virtual interface.
AddressLessIf	Interface index.
PacketSrc	Source IP address of the packet.
ConfigErrorType	Error type. [1] The OSPF version are inconsistent. [2] The area configurations are inconsistent. [3] Unknown NBMA neighbor. [4] Unknown virtual neighbor. [5] The authentication types are inconsistent. [6] Authentication failed. [7] The network masks are inconsistent. [8] The configured Hello time periods are different. [9] The configured Dead time periods are inconsistent. [10] The Option field are inconsistently configured. [11] MTU configuration inconsistency. [12] Router ID configuration conflict. [13] Unknown error.
PacketType	Packet type ID. [1] Hello. [2] DB Description. [3] LS Request. [4] LS Update. [5] LS Acknowledge.
ProcessId	Process ID of the local device.
AreaId	Area ID.

Possible Causes

Cause 1: Interface parameters configured on the two interfaces for establishing the OSPF neighbor relationship were inconsistent. Cause 2. The link-layer protocol changed.

Procedure

1. Run the display ospf interface command to check whether the configurations on the two interfaces are consistent.

If the configurations on the two interfaces are consistent, go to Step 3.
If the configurations on the two interfaces are inconsistent, go to Step 2.

2. Do as follows based on the networking:

If the networking allows you to modify the configurations on the two ends to be consistent, go to Step 3.
If the networking does not allow you to modify the configurations on the two ends to be consistent, go to Step 4.

3. Modify the parameters of the hello, dead, and poll timers on one end to be consistent with that on the other end. Then, check whether the alarm is cleared.

If the alarm is cleared, go to Step 5.
If the alarm is not cleared, go to Step 4.

4. Contact contact technical support personnel.

5. End.
