Can you describe which ?

1. A community has agreed to only use one channel/bssid/netmask/broadcast) for 

2. consider a wireless scenario like this:


where A, B and C are locations with mesh nodes.
The distance between A-B can only be made with a directional antennas.
B should also have a omniantenna to serve other local nodes (like C).
Therefore I want to configure node B with two radio interfaces.
Also imagine a node D appears in the line between A and B with physical 
connectivity to B0 and B1 !

Sorry, I'am still unsure if i understand correct. So you mean olsr should be 
able to handle such situations without problems?
Or is it more that such case is not foreseen and therefore not expected to 
work properly. 

Thanks a lot,
