Hi!
CCing Faidon if it's urgent as I'll be out next week.
A /64 for the transport network and a /48 per cloud environment (/site)
sounds good to me. Exact prefixes TBD but it should be quick to assign.
I don't know (yet) what's OpenStack best practices for v6 but I can
probably do some research as well. Instinct tells me that splitting the /48
is more future-proof.
About OKRs, please let me know in advance so I can prioritize accordingly :)
Related, I still have to create a Google doc to strawman/discuss dedicated
hardware (switches, routers).
Cheers.

Hi Arzhel,
now that our BGP thing is mostly working, I think we can move forward with
IPv6
for codfw1dev, which was my original intention before doing anything
related to
BGP :-P
We would need to:
* allocate a small IPv6 prefix for the transport network (between cr-codfw
and
the neutron virtual router). I'm open to suggestion to the size of this
subnet.
* allocate a big IPv6 prefix that we could use internally inside the cloud
environment (for VMs). This should probably be a /48? I'm not sure yet if I
would be doing subnetting of this big prefix and allocate smaller ones
(/64) per
project, or if we will be using the big one directly without
sub-delegation.
(Something to research anyway).
I will follow-up next week. For the record, doing this research and design
is
one my goals/OKRs for this quarter (3 week left!). My plan is to use this
wikitech page as my deliverable:
