Hello,

In the documentation was written that a specific TTL can be assigned to each interface. How can I do this from command line? I have two interfaces eth1 (wlan) and bbs (a VPN tap tunnel used as backbone).

Those interfaces are not bridged and have different ip ranges eth1: 10.12.x.x bbs: 172.16.x.x

My aim is only to propagate the 10.12.x.x ip range and not the 172.16er. The 172.16 of any foreign router should not be listed in any routing table of any other router. Only the local interface address of bbs should be seen in the routing table. I have read that this can be solved by setting the TTL for bbs to a value of 1. I need to know how I can do this.

We removed this feature from the stable branch because many people were confused when using an interface with a small batman-ttl for outgoing traffic. In such case, the destination node of the traffic does not know where to reply. In general, no problems occur if the (two-interface) node is not generating traffic itself

Currently a -t option is included in trunk/batman-experimental which allows to specify the ttl to be used for all interfaces. Applying different ttl-values for different interfaces conceptually works but setting these values with the command line is on the TODO list.
