I think we're an ISP (AS559), and we don't have any equipment that would be unable to filter against spoofed source addresses. In fact I think that even seven years ago all our equipment could do this. Yes, I know about certain "Engine-N" generations of certain linecards for certain "high-end" routers, but my sympathy to those ISPs who still use them is limited. (Especially with those ISPs that keep a few in their network just as an excuse for not deploying BCP39 anywhere :-) -- Simon. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
