EZZ7922I
Bad length Link state advertisement received from neighbor

Explanation

A Link State Update packet was received from the specified neighbor. OMPROUTE determined that the link state advertisements (LSAs) contained in the packet had one of the following problems:
  • The sum of the length values specified in the headers of the LSAs contained in the packet exceeds the length value specified in the OSPF header of the packet.
  • An LSA header length field value is smaller than the length of the LSA header.
  • The number of elements in an LSA does not correlate with the LSA header length field value. An example of this is a Router LSA that specifies an incorrect value for the number of links that it contains.
In the message text:
neighbor
The IP address of the neighboring OSPF router.

System action

The LSA is discarded.

Operator response

Contact the system programmer.

System programmer response

Contact the manufacturer of the OSPF application on the source router to report the problem. For additional information, including instructions on gathering documentation, see diagnosing OMPROUTE problems in z/OS Communications Server: IP Diagnosis Guide.
