Batman adv over powerline

Installing and Using OpenWrt Network and Wireless Configuration
21

I have tried a similar setup at another place (spoiler - didn't work):
Obviously the versions are different but I am not aware of any major changes regarding batman. Does anyone may have a hint how to properly monitor what batman is doing on the link layer by batctl td or comparable tools?

batctl if

  1. eth0.1: active
  2. eth0.3: active

Using ip addr the interface masters are set like my uneducated mind would consider it correct.
Sadly batctl n still does not show anything.

I am pretty confident that I set the VLANs correctly but maybe some notices something. I will go on and create another post now asking for specific help.
