...to discover that I was offering the shortest path
to the exit
nodes, and thus had bypassed the two existing ~50mbit links into lab
links that were located indoors and going through a thousand+ meters
of trees... that was barely doing a megabit with 800+ms of delay.
What was the issue? No multicast loss on the link? I find that difficult
to believe.
(channel diversity not working did not help either)
Not sure about that -- if computing the channel number fails, babeld will
assume that the link interferes with all other links, so the misconfigured
link should be disfavoured.
I'm sure you already know that, but until I get around to rewriting the
channel determination code for recent "we don't break userspace" Linux,
you can work around it with manual configuration:
interface wlan42 channel 42
After that experience, I decided that I would make the
firmware for
unconfigured nodes export a 512 metric,
Good plan, although I'd make it 32000. This way it'll be easy to spot an
unconfigured node in BabelWeb.
Note that if you do that, you should apply it at the metric level, not at
the
