So, basically you want to have ppp running with unnumbered links, and then
maybe you do routing over that?
I am not surprised that this hasn't been tested, and that there are bugs.
Mostly, IP6CP assigns random IPv6-LL.
I guess it does surprise me that there are bugs! I had been assuming
that I was doing something wrong but the more I look at it, the more it
looks like a bug.
If your goal is routing over unnumbered links, you don't really need the
destination IPv6-LL to route to, it's enough to "dev ppp0" or whatever.
Yeah, that is perfectly fair. I did get static global IPv6 addresses and
routing working, so the actual link-local address I guess isn't that
important.
Just a bit frustrating not being able to achieve something that seems
like it should be possible.
Thanks!
