I'd like to point out that if people think that PI (and placing 1 or

Actually it doesn't. It's very hard to qualify for a /22 so
effectively this only helps Big Content. The issue of smaller ISPs or
whole sale transit carriers that don't give out address space to
their customers because those all have PA isn't addressed here.
But it completely changes the game: why spend time on deploying shim6
if you can round up your IPv4 needs to get to a /22 or lobby for
reducing the /22 requirement?
So there are only two questions:
1. Is there sufficent need to continue shim6 for a no-frills easy
multi-homing solution for consumer and small business customers
or won't support BGP?
2. Are people concerned with the long term implacations of de-
for multi-homing, and if so, then should we pursue a protocol solution
that has full support for TE in an effort to replace de-
aggrgegation as a
solution and halt (or possibly reverse) the growth of the routing
Let me add a third question: will shim6 be deployable when people can
Maybe shim6 can still do some good but we really need to rethink our
goals here. I was uncomfortable with moving fast and only
implementing bare bones mechanisms before, and even more so now. We
should slow down and get it right the first try because if there is a
place for shim6 in a world with IPv6 PI, that place is for a GOOD
shim6 solution that solves the problem well, something that kinda
works just to get something out the door isn't good enough and there
won't be a second chance to come up with an improved version.
BTW, I was one of six people who voted against moving forward with PI.
How many people voted in favor?
