The host should, I should think, set the hop limit to one on any packet that is to a link-local address, to ensure that the packet is not repeated by a broken router (apart from protocols that ask to have it set to 255 and have the receiving host check for that value). Also, upstream network's BCP 38 implementation sounds suspect, and I'm with Jen in wondering why a router forwarded the packet in the first place. > > Are you sure these packets come from hosts?

I saw packets with link-local source/GUA destination coming from hosts and from routers (I analyzed EUI-64-based IIDs) back in 2011. Now majority of such traffic is TCP to our services and, again, IID checks shows that these packets are from hosts. -- SY, Jen Linkova aka Furry
