according to your logs OGMs from b0:c6:9b:80:01:43 are received via nodes that 
are not in your routing table either:
 * b0:c6:9b:80:01:57
 * b0:c6:9b:80:01:6c

Therefore you see the warning: Drop packet: OGM via unknown neighbor!
Batman-adv can't create a route to a an originator without having a next hop. 

Do all nodes in your network run the same batman-adv version (2012.0.0) ?

Marek
