[6bone] RFC 2772 input from RIR space holder

Hi,
Going to reply to Robert's mail that never got the attention it
deserved. It is very important to understand why RIR space
holders care about RFC 2772.
We make living out of selling/providing services over Internet,
we are totaly depended on what people call production quality
or reliable routing. It's not just a word for us, it's our life
as a provider we're talking about.
We can assume that most of the services that will be important
from a business perspective will be using RIR space.
Think we also can safely assume that RIR space are for
production services (as said above), and 6bone space used for
experimental/learning/testing purpose.
This isn't just the view of one single sTLA holder, it's a view
I know is shared by many others. How to create a stable IPv6
network are The Focus for many big ISP's with sTLA right now.
There are work in progress to create guidelines and later I
guess it might be an official document covering the routing
issue in RIR space. We will sort ourself out...the issue is
6bone routing. We do NOT want 6bone to have ANY impact on our
business at all. That's pretty much the bottom line. Robert
outlined one way to gain this in his mail (see end of mail),
the following part are a suggestion from me, it's build on
the frame Robert outlined.
---
to keep it simple:
* 6bone sites can announce each other their pTLA route within the
3ffe::/16 cloud including _one_ default 2001::/16 route.
Then we need a extra addon to this to avoid causing never ending loops:
* A site can ONLY announce the default RIR prefix to other peers
IF they have the more specific RIR prefixes in their table.
example, I'm a pTLA with no connection to RIR space and should have no RIR
prefixes in my table, in this cause I can NOT provide transit to RIR
space to anyone else than my endusers. Or in other word, I can not provide
RIR space transit to other 6bone sites....
The advantage of this:
- 6bone/RIR space will become two separate network that can NOT break
each other, we (RIR) can guaranty routing easier.
- 6bone can do as much experimental stuff as they want to, they can still
NOT harm production traffic (production traffic should anyway ALWAYS
go over and use RIR space)
disadvantage:
- it add a bit more complexity to the routing but think what we gain
from it are more important.
- longer routing in general when you're going RIR <> 6bone space.
It basically give us the chance to make a quality production IPv6
network AND still be able to do experimental stuff on 6bone without
impact on each other. it also give us (RIR) the chance to guaranty
routing in RIR space, or to say it as manager:
"we can provide production quality on our IPv6 network"
thoughts?
