It will work. But please note that you are supporting a single layer 2 broadcast domain in this case. This might be OK for you (I know ISPs where *everything* is bridged) - as long as your links have a high capacity and they are stable. In my experience things can get a bit tasty if you have too many broadcast storms. In addition here is something which might be helpful for you: the new etx_ffeth metric: You might want to tune your links with the mode "mesh" or mode "ethernet" parameters and the etx_ffeth metric in olsrd.conf. See files/olsrd.conf.default.lq for a good description. The etx_ffeth metric is new in 0.6* and basically treats wired links as links with ETX metric 0.1 . Which makes them the prefered routes . So the idea is to stay on the cable as long as you can. Note that etx_ffeth is not compatible with the previous etx_* metrics.
