Could this be the exactly the NOD flag?
If modifying this flag breaks routing then this IS a strong hint for 
influencing routing. Could it be that in this byte one bit is the flag 
for the presence (or absence) of the NOD table? If this bit is 
set/cleared then it tells the device that there is no NOD table and 
therefore no routing is possible.
