%OSPF-4-BADLSATYPE Error Message

The full text for this error message is as follows:

    %OSPF-4-BADLSATYPE: LOG_WARNING: Invalid lsa type [dec] in LSA    [dec], [dec] from [dec], OSPF_COMPLAIN-IVL 

Explanation: The router received an LSA with invalid LSA Type. The cause is either memory corruption or unexpected behavior on a router.

Recommended Action: From neighbor address, locate the problem router and reboot it. To determine what is causing this problem, call your technical support representative for assistance.

%OSPF-4-CONFLICTING_LSAID Error Message

The full text for this error message is as follows:

    %OSPF-4-CONFLICTING_LSAID: Found lsa type [dec] in LSA [inet]    [inet] from [inet], [chars] 

Explanation: An internal software error occurred.

Recommended Action: Copy the error message exactly as it appears, and report it to your technical support representative.

%OSPF-4-ERRRCV Error Message

The full text for this error message is as follows:

    %OSPF-4-ERRRCV: Received invalid packet: [chars] from [inet], [chars] 

Explanation: An invalid OSPF packet was received. Details are included in the error message. The cause might be a misconfigured OSPF or an internal error in the sender.

Recommended Action: Check the OSPF configuration of the receiver and the sender for inconsistency.

%OSPF-3-INTERNALERR Error Message

The full text for this error message is as follows:

    %OSPF-3-INTERNALERR: Internal error: [chars], OSPF_COMPLAIN_IVL 

Explanation: An internal software error occurred.

Recommended Action: Copy the error message exactly as it appears, and report it to your technical support representative.

%OSPF-3-NOBACKBONE Error Message

The full text for this error message is as follows:

    %OSPF-3-NOBACKBONE: Flagged as being an ABR without a backbone 

Explanation: The router was flagged as an ABR without backbone area in the router.

Recommended Action: Restart the OSPF process.

%OSPF-3-NOCONNDB Error Message

The full text for this error message is as follows:

    %OSPF-3-NOCONNDB: No database entry for connected address [int] 

Explanation: While calculating OSPF routes, the router could not find the LSA that represents the connected route in the router.

Recommended Action: Clear the IP routes in the routing table by entering the command clear ip route.

%OSPF-3-NOLSA Error Message

The full text for this error message is as follows:

    %OSPF-3-NOLSA: Failed to find this router LSA in [chars] 

Explanation: The router is not able to find its own router LSA. This can occur occasionally and self-correct. However, if this message recurs, restart the OSPF process.

Recommended Action: Copy the error message exactly as it appears, and report it to your Cisco technical support representative.

%OSPF-3-NOMEMORY Error Message

The full text for this error message is as follows:

    %OSPF-3-NOMEMORY: No memory for [chars] 

Explanation: The requested operation could not be accomplished because of a low memory condition.

Recommended Action: Reduce other system activity to ease memory demands. If conditions warrant, upgrade to a larger memory configuration.

%OSPF-4-NONEIGHBOR Error Message

The full text for this error message is as follows:

    %OSPF-4-NONEIGHBOR: Received [chars] from unknown neighbor [inet] 

Explanation: The OSPF hello, database description, or database request packet was received, but the router could not identify the sender.

Recommended Action: This situation should correct itself. If the message recurs, call your technical support representative for assistance.

%OSPF-4-NORTRID Error Message

The full text for this error message is as follows:

    %OSPF-4-NORTRID: Could not allocate router ID 

Explanation: OSPF failed while attempting to allocate a router ID from the IP address of one of its interfaces.

Recommended Action: Make sure that there is at least one interface that is up and has a valid IP address. If there are multiple OSPF processes running on the router, each process needs its own unique router ID. You must have enough “up” interfaces so that each of them can obtain a router ID.

%OSPF-6-NOSRCPDB Error Message

The full text for this error message is as follows:

    %OSPF-6-NOSRCPDB: ex_route_callback(): Can't find the src    protocol to redistribute net [inet] [inet] 

Explanation: OSPF attempted to redistribute a route but could not fine a valid source protocol.

Recommended Action: No action is required.

%OSPF-6-NOTREDIST1 Error Message

The full text for this error message is as follows:

    %OSPF-6-NOTREDIST1: ex_route_callback(): do not redistribute net    [inet] [inet], [chars] 

Explanation: For information only.

Recommended Action: No action is required.

%OSPF-6-NOTREDIST3 Error Message

The full text for this error message is as follows:

    %OSPF-6-NOTREDIST3: build_ex_route(): don't redistribute net [inet]    [inet], [inet] advertises it already 

Explanation: For information only.

Recommended Action: No action is required.

%OSPF-4-NOTREDIST4 Error Message

The full text for this error message is as follows:

    %OSPF-4-NOTREDIST4: Database scanner: external LSA [inet] [inet] is    lost, reinstalls 

Explanation: The software detected an unexpected condition. The router will take corrective action and continue.

Recommended Action: Record the entire error message and note any OSPF problem you experience. Report the error message to your technical support representative.

%OSPF-4-NOTREDIST5 Error Message

The full text for this error message is as follows:

    %OSPF-4-NOTREDIST5: db_free: external LSA [inet] [inet], 

Explanation: An internal software error occurred.

Recommended Action: Copy the error message exactly as it appears, and report it to your technical support representative.

%OSPF-4-OSPFINTDOWN Error Message

The full text for this error message is as follows:

    %OSPF-4-OSPFINTDOWN: Interface [chars] is up but OSPF state is down.    Clean up, OSPF_COMPLAIN_IVL 

Explanation: An inconsistency in an internal state was found and corrected.

Recommended Action: Informational message only. No action required.
