[Olsr-users] OLSR without ad-hoc mode?

Olsrd (and Olsrd2) should work with any kind of layer3 network that
supports broadcast or multicast...

you can use adhoc, you can use accesspoint/station mode, you can use
ethernet or even VPN connections... as long as it has multicast its no
problem at all. Without multicast it does only work well for
point2point links and you have to preconfigure the IP of the other
