In my deployed babel network... I am dreading the source specific
change. But I've been prepared to have that flag day for three years,
and the ietf processes make me crazy. I have no less than 6 deployed
versions of babel in the field (and I mean, in the field, in trees,
and on rooftops), spread across 40+ routers, it will take me months or
years to replace them all... and the deployment strategy juliusz has
outlined is acceptable.

In part due to the lack of a good ipv6 address distribution mechanism
(slight dig), very little of my network is ipv6 enabled, and the sad
way I assign source specific addresses now (ip route show |  grep
"from" | pickaddresseslikeslaacdid), ipv6 source specific connectivity
either comes back on the reflash/reboot or it doesn't - and ipv4 keeps
working. The ipv6 stuff has largely not escaped the lab due to the
delays in standardization.

due to the address assignment problem, I think very few babel
installations are using ipv6 all that much, except in non source
specific ways.

Let's just get it over with and get the documents AND code out there
already. openwrt 18.06-rc2 is out now and it would be great to start
testing al the new stuff before it goes final. Warn people in the
README.

If this were OSPF or BGP or ISIS I'd care more, but babel's deployment
is at least 3 orders of magnitude smaller than those.

ship it. Move on.
