sure, because OLSR distributes the routes.

That's what i prefer to do :)

should be prossible. If you are more specific then maybe someone here
has an idea why its not working.

YES YES YES :)

In Vienna we created an automatic build environment.
people come to us with a linksys and we enter their data. Then on our webpage
there is a button "build firmware" and it gets built.
Then the user gets an email with an URL. he/she then downloads the firmware
and flashes it onto the linksys. voila! instant turn on mesh routing.
so far very effective.
> 3) What am I doing wrong with OLSR Switch, and how do I debug?
there could be many reasons. if you have more specific info (i.e.
IP setup etc) then it is easier to analyze.
