Probable VLAN fix

by Gioacchino Mazzurco

Hi all! Talking with some german guys they were having fun on me, because i said tagged vlan are not working on wdrXXXX switch it seems we are just ignorant and we are missing some knowld on how switch works on openwrt they said to me that they tried on wdr3600 and it works fine and pointed to me to this page http://freifunk.in-kiel.de/wiki/Konfiguration/Eigenes_WLAN I do not have tp-link with me but i'll implement that as soon as possible and hope someone with tp-link in hand can help me testing

br-lan: received packet on bat0 with own address as source address

by Ilario GELMETTI

Hi all, I have two devices (Ubiquiti PicoStation M2 and Ubiquiti NanoStation M5) in a very simple configuration: both attached to a Mikrotik RB250GS gigabit switch (latest 1.11 firmware) and both running the latest libre-mesh firmware. >From dmesg of the two devices I can see some error form batman loop avoidance: br-lan: received packet on bat0 with own address as source address Do you think that could be a libre-mesh related problem?

Again, I don't know if this is a libre-mesh related problem or a problem of batman loop avoidance. Maybe the problem is related to this old closed bug? http://www.open-mesh.org/issues/170 Thanks, Ilario
