Someone posted a message regarding this, and I accidentally deleted it. But, I think I can help. The two addresses OSPF are complaining about are the class D multicast addresses that OSPF uses to send Hello packets and Link state updates to. 224.0.0.5 is the universal OSPF address. All OSPF routers should be able to listen at this address. 224.0.0.6 is listened to by designated routers and back designated routers. This explains why you have so much usage on 224.0.0.5, and very little on 224.0.0.6. However, the reason you're getting errors in your log file could be due to an error in gated. OSPF does require an interface configured with IP in order to run. On networks that support multicast (i.e. ethernet) OSPF maps IP multicast addresses to MAC addresses. If you don't have an ethernet card configured for OSPF, this could also be why you're getting the errors.
