yeah, "WDS" must always be enabled on all bridges (in some AirOs versions is called "Transparent bridge mode") or funny things happen in IPv6 world > Also, some nodes running olsr2 do not have a connection to the rest of the > olsr2-could.

Details see this github issue: > https://github.com/OLSR/OONF/issues/10 i'm using a seemingly old version 0.9.2: stein712# olsrd2 --version OLSRd2 version 0.9.2 Git commit: v0.9.2-archive and i communicate OK with gri106 (and i get routes for 'gri121' and 'test') so i assume gri106 (and the others) are also using olsrd2 <= 0.13.0 looking at the map you provided, and comparing with OLSR1 (ipv4) map: http://ff.cybercomm.at/map/ an explanation would be that some ubiquiti in the way between 'gri106' and 'mh' is missing the "WDS" / "Transparent bridge mode" activated CC'ing here the tech-c of both nodes, to see if we can solve it together :) > > I hope this helps to explain the situation. > To solve this for you, I propose to get in contact with the node owner/tech-c > of gri106 and his/her uplink-partner. > > Stein712 has node-id=2843, that is 0xb1b. > Your node's IPv6 user block therefore is: 2a02:61:b1b::/48. perfect, will use that Thank you so much Christian for all the debugging tools and information!
