I wonder the reasoning behind section 2.8. of draft-martin-deploying-ipv6-=
data-center<https://datatracker.ietf.org/doc/draft-martin-deploying-ipv6-da=
ta-center/>?
Normally IPv6 default router is learnt from router announcements.
Why a good practice would be to place the default gateway at fe80::1?
What if the server node has multiple links?

Hi all,
Please find version -01 of those drafts:
* draft-martin-deploying-ipv6-data-center<https://datatracker.ietf.org/=
doc/draft-martin-deploying-ipv6-data-center/>
* draft-martin-retry-over-ipv6<https://datatracker.ietf.org/doc/draft-m=
artin-retry-over-ipv6/>
Many thanks for the comments and the contributions (each one is on a github=
repo)
for retry-over-ipv6 I did an experiment on 6/6 on pacific.ipv6forum.com whi=
ch brought a few data points (and all kind of comments on the Internet). Ne=
xt IPv4 outage on this site is for July 6th. Be ready to try!
Most of the discussion and comments are happening on v6ops WG.
I appreciate if folks from the httpbis WG would check the second ID as it i=
ntroduces the 566 error
For the first ID, it is a v6ops goal to publish an RFC on this topic by the=
end of the year. I'm trying to find more co-authors. I have reached to fo=
lks that I know have deployed large IPv6-only environments, but your help i=
s appreciated in pointing this document to them.
