Hi,
I think the List had issues with all of us getting
multiple emails for
some reason. I wanted to update you on this status and let others know
about my solution.
yes, mailman was standing still due to a deadlock. Sven had to restart mailman
before all the sent mails were processed. Seems some people were getting
impatient .. ;-)
I had to enable STP on the lan-switches. STP type:
STP and Mode: Root
Protection. This can be enabled on all ports safely without causing
disruption to the clients plugged into the switch.
After this step was done, bridge-loop-avoidance worked properly and if
more than 1 router in a mesh was plugged in, all the routers would pick
one as a gateway.
I don't know much about STP (root protection does not tell my anything) but
using STP seems like a very bad idea. STP does not know a thing about your
mesh network and the qualities of the links. To avoid the loop it will simply
turn off "ports" in the router which certainly is not what you want. At some
point in time it might decide to turn off a port you are using ...
I re-read all the mails but I still can't understand your logic: You have 2
batman-adv gateways that announce the wired clients via HNA. This happens to
allow wireless clients connected to the mesh to communicated with your wired
clients. No problem here. Why do you think the packets go through the mesh ?
If more than one is plugged in, the higher MAC router
will drop all lan
packets which will result in slower throughput to clients to that router
because it is hopping to another router via wireless and neglecting the
fact that it's own wired link would take it faster to the intended
destination.
Are you talking about the bridge-loop-avoidance ? What makes you think they
are using the wireless interface to forward the traffic to the other gateway ?
My "solution" to this was to enable STP in
the router too.
Again, using STP on top of batman-adv will create more problems than it
solves.
Regards,
Marek
