[f-nsp] OSPF neighbour problems

[Mark Tech]

Hi
  I connect an MLX-4 to a Cisco 7200 router through an Ethernet point to point connection. This has been working well for several weeks until yesterday when all of a sudden the OSPF adjacency seems to have a problem i.e.
   
  Dec  9 12:53:54:D:OSPF: rcv BAD Checksum :  2  4  0 40 c3  e 5f fa  0  0  0  0 a9 c4  0  0  0  0  0  0  0  0  0  0  0  0  0  1  e 10  2  5 c3  e 48 8d c3  e 53  4 80  0  0  2 3e  2  0 24 ff ff ff ff 80 ff ff ff  0  0  0  0 b0 23  
   
  Dec  9 12:31:05:N:OSPF: intf rcvd bad pkt: Cannot associate neighbor, rid x.x.x.x intf addr y.y.y.y, pkt size 124, checksum 832, pkt src addr z.z.z.z, pkt type link state update
   
  Does this point to anything obvious, my 1st thought is that the carrier Ethernet is malforming the OSPF packets somehow, any thoughts?
   
  Regards
   
  Mark
