hi,

if the hello interval on both sides (the main router and its neighbor) does not match, there could such an error.

I am not sure, it's the reason why you are encoutering this error

May somebodey else help you deeper.

Error Message

%OSPF-4-BADLENGTH : Invalid length [dec] in OSPF packet from [int] (ID [int]), [chars]

Explanation The system received an OSPF packet with a length field of less than normal header size or inconsistent with the size of the IP packet in which it arrived. This indicates an error in the sender of the packet.

Recommended Action Copy the error message exactly as it appears on the console or in the system log. Issue the show tech-support command to gather data that may provide information to determine the nature of the error. If you cannot determine the nature of the error from the error message text or from the show tech-support output, call your Cisco technical support representative and provide the representative with the gathered information.
