Just realized I replied to Shyam instead of the list. So here goes :

>> Hi Sebastian/ Johannes,
>>
>> I have three nodes (A, B, C) running ibr-dtn. I would like the packets to be forwarded from A->B->C and C->B->A but never directly from A->C or vice-versa. How could I achieve this? I wonder if the static configuration can help me and if this can be setup via the configuration file? I couldn't find the answer to this in the forum.
>>
>> In the configuration file, I see two parts relating to static configurations: 
>>
>> # route all bundles for "~dtn://*.moon.dtn..." via "dtn://*..." 
>> route1 = ....
>>
>> ### node-five.dtn###
>> static2_address = ....
>> .....
>>
>> 1) Could you tell me if this is possible to do?
>> 2) Could you give me an example of how to set this up?
>> 3) The static URI is ended with .dtn. Why is this necessary? The dtn address on my nodes is like dtn://OpenWrt20, dtn://OpenWrt30, etc.
