This is two times the same node, first time it recognizes the broadcast
the right way, second time not.

Is this implemented like this (where?)? Can't work BATMAN with the
interfaces (or can't we change it to work this way), it would make the
whole configuration much easier to assign to every node only one single
IP address (or two, one for olsr and ne for BATMAN)? We are doing this
with olsr and this really makes the network-structure much cleaner -
every node has one IP.

Is the described problem with the misconfigured broadcast related to the
'same IP on different interfaces' issue?
