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 _______________________________________________ rtgwg mailing list [email protected] https://www.ietf.org/mailman/listinfo/rtgwg
