Hi,
I know bridging is not routing but I was thinking since some time if it is possible to modify the linux bridge-code for forwarding layer2 packets according to the rules of some routing algorithm. This means the bridge would not learn mac addresses from ARP protocol any longer but from a daemon. The result would be a layer2 mesh routing like BATMAN does.
OLSR is doing quite the same one layer above by manipulating the routing table with the OLSR daemon. Of course it's much easier to manipulate a routing table because there are interfaces for doing this.
It's just an idea and I would like to hear your expert opinions.
Kind regards, Franz

if you want something like BATMAN why not simply using BATMAN ? Or you are trying to understand the difference between standard bridging and BATMAN ?

unfortunately I am stuck with an older kernel where I can't use BATMAN. And everytime I am dealing with linux bridge configuration this idea comes into my mind.
At the moment it's just an idea but before starting some experiments I would like to get some feedback.

If you can't upgrade your kernel you need to develop that for your old kernel version. BATMAN supports up to 2.6.21 which already is ancient ..

Then you have to explain your idea in greater detail. Feeding mac addresses into the bridge module alone is not going to make layer2 routing work.
