when will vendors learn that punting to the RE/RP/smarts for packets in the fastpath is ... not just 'unwise' but wholesale stupid? :(
What to do with IP options or IPv6 hop-by-hop options? What to do with IPv6 packets which contain options which push TCP/UDP past your lookup view? Punting transit is not only not stupid but also necessary in hardware routers which cannot handle every case in hardware (which is all routers). There should just be adequate way to limit these and there should exist default limitation. -- ++ytti
