[lime-dev] bridge and batman-adv over ethernet

Hi! We are currently trying to use the Libre-Mesh.org firmware with batman-adv enabled on wired Ethernet interfaces alongside with a VLAN which is a member of the bridge the batX interface also resides in. ------------------------------ E |VLAN---batadv---bat0 T +--------------+ BRIDGE H |VLAN------------eth0.xx ------------------------------ We do want such a setup to have the best of both worlds: the performance of a plain bridge but yet benefit from batman-adv topology information, alfred and all that. As many cheap Ethernet switches do not support frames larger than 1500 bytes, increasing the MTU is not an option and thus frames inside batman-adv end up fragmented which hurts performance if encapsulating all traffic via batman-adv. I remember there was a discussion during battlemesh about a race- condition which can confuse BLA and thus batman-adv is still disabled on wired Ethernet interfaces in Libre-Mesh by default. So here I am asking you about the current state of affairs regarding this issue. We are discussing it on https://github.com/libre-mesh/lime-packages/issues/56 and it would be great to hear a more detailed summary because I only remember the rough details and also haven't been watching if anything was fixed or improved since we all met in Porto. Cheers Daniel
