Ah, ok, that's an LCP option so it covers the hardware side of
things. Still better to have different maximum packet sizes for v4
and v6, though.
2. DNS resolver addresses. Without the ability to resolve names
IPv6 is

use the same mechanism as on any other IPv6 link. i.e DHCP.
That's insanity. I'm not even going to bother discussing such nonsense.
Currently, the interface identifiers in IP6CP and standard autoconfig
allow for the creation of addresses 3 and 4, but what we really need
is a prefix that holds addresses 1 and 2.
DHCP prefix delegation.
Well, I don't have to implement this stuff so maybe I shouldn't
complain. But if I did, I know that I wouldn't want to implement both
versions of DHCPv6, include moon phase sensors to decide which
variant to use and then execute it after I've done PPP and stateless
autoconfig negotiations if the alternative is defining one little new
NCP option.
I can't stress enough that IPv6 over PPP in its current form is as
good as
unusable in practice, and this draft doesn't fix that.
none of the arguments you've put against PPP don't also equally
apply to
any other IPv6 link type. and we already have the solutions.
Wearing a protocol designer hat that's true, if you don't mind
running a bunch of protocols, wearing an operator or end user hat you
only see boxes that talk to each other and then fail to do for IPv6
what they've been able to do for IPv4 for the past decade and a half.
We only have a bunch of partial solutions and the parts don't fit
together particularly well even in theory, and not at all in practice
in current implementations.
But apparently nobody feels responsible for the thing as a whole. My
conclusion is that if you want to do IPv6 over PPP, you should run
IPv4 over PPP and then tunnel the IPv6 over IPv4. Anything else only
leads to headaches.
