I look forward very much to doing more of that... after lede ships.

In the interim, I have two fairly large testbeds setup to test lede -
the ATF patch, the dnsmasq-dnssec code, the bcp38 code, the dhcpv6-pd
code, the new bridging code, and babel integration are all high on my
list, along with sch_cake and the sqm-scripts. I have 5 lede platforms
under test - the archer c7v2, wndr3800, linksys 1200ac, uap-lite, and
picostation, with two more that I plan to add after testing interop
(edgerouter and an apu2). There are also 3 different brands of
cablemodem in the loop. Test clients include a dozen hackerboards
(kernels going back to 3.10), OSX, and Linux.

I'm perpetually testing edge cases and things that seem like they
should work, but don't. While things are vague and confusing (like,
babel-1.8's behavior being confusing in some instances) - and a piece
of a puzzle lands (like not restarting it as much, thus causing less
route retractions and floods) - I do tend to dump partial state about
the rathole I may have been going down.

I've been trying to come up with tests for understanding the true
effects of the multicast-unicast bridging code, for wifi primarily,
and simplifying. At the moment I'm more trying to test 3 layers of
lede dhcp-pd (bridged and routed scenarios) across gear that needs to
interop...

... instead of dealing with how all that feeds into babel source
specific routing - which is a combination of interactions between
netifd, babeld, and multicast/bridging.

If these projects want to write "no cross posting ever" into the
rules, I will gladly comply.

I hope you get your caps-lock key fixed.

I'm going to just filter out all further postings from you into my trash folder.
