If switching to 2011.0.0 helps, don't read any further :).
Could you explain a little more which interfaces you've added to
batman-adv and which interfaces you are bridging with bat0?
(ifconfig, brctl show, batctl if output from one router would be
Our Network configuration:
8 batman-adv routers with a wireless mesh with two or more of the
routers having a wired connection directly to the switch. In this
case, the 8 routers decide to pick one of the "plugged in" routers
as a gateway to avoid bridge loops. This is fine.
I have been running into issues with wired clients however.
When a wired client plugged into the switch tries to contact a wired
client plugged into the same switch, the packets manage to get lost.
I believe they are are going through the wireless routers plugged
into the same switch.
Instead of going like this..
PC 1 ----> switch1 ---> PC 2
they seem to be going like this... (my guess).
PC 1 ---> switch1 ---> wireless router 1 ----(wireless mesh
link)----> wireless router 2 ----> switch1 ---> PC 2.
Could you please
verify with "batctl td" (or tcpdump/wireshark) if
the packets are leaving on the wireless router 1's wifi interface?
I think this is because the translation tables on the bat node are
announcing that even the wired clients are connected to them.
Could you check with
batctl tl and batctl tg if these tables are changing
rapidly? If you do not have any client roaming, then these tables are
expected to stay rather static.
This is causing extreme delays even in wired clients. Any help will
be appreciated. Should I enable STP in on the switch ports ?
It does not sound like
having disabled STP is your problem.
