The point I am making is that the solution is still the same - filtering in ethernet devices.
No. I agree that in some enviornments DHCPv4/DHCPv6/RA filtering are going to be a requirement. If I was running the NANOG network, or a campus network for college students I would insist on such. However, there are many enviornments where that is not a justified expense. At home I have a dumb, unmanaged switch which serves my family just fine. I'd rather like it that if I plug in an unconfigured router to configure it for something that it not take my wife offline. The DHCPv4 model works great for this, there are no issues and I don't need a managed switch. IPv6 takes that option away from me. My only option is an expensive upgrade to the switch and a bunch of manual configuration. DHCPv6 needs to be fixed before it is deployed. Dependance on RA's needs to be removed, and a standard option for a default route needs to be added. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
