I've noticed something similar in a lab when running OSPF between a IOS
router and Windows 2000 Routing & Remote access running OSPF.
OSPF would not come up between the two. Every ten seconds I would get
the following error in the Windows system-event-viewer:
"Rejected an OSPF packet from 10.0.0.4 to 224.0.0.5 because the OSPF
data length in the OSPF header was 44 but the length calculated from the
IP Header fields was 56. "
I can't recall whether or not there was any authentication taking place,
but the fix was the same as in the link provided below.
Router ospf 1
no capa lls
Thanks,
Curt
