[OLSR-users] olsrd with 2 networks

a typical mesh network will need a default route, because there is an inet 
gw. It's irrelevant what program configures the defroute. An untypical mesh 
does may not need a default route - e.g. Routers in most AS (Autonomous 
Systems) do not use such a thing AFAIK (which one of the connected network 
is *default*!?)

All network traffic destinned to adresseses not in the mesh will be routed 
to default and discarded by a typical provider to /dev/null or (more badly) 
to /var/log/intruders if you use non-inet IPs in your mesh. If you run your 
ifaces with the correct netmask, a local device will ARP for a non-avail 
station and put local traffic to the local /dev/null...
