Let me take the 2nd item: Independent of LLS, OSPF uses the IP protocol, and the IP protocol is a best effort protocol. Second, even if the OSPF pkt is delivered to a destination, the network interface may itself drop and or reject it, because of exaustion of resources, i.e, recv descriptors and / or socket or mbuf network buffers. This is even before the destination's OSPF recv's the pkt.
