I'm not sure but I would think netcat or iperf do not look
at the routing table.

Looking at the help text (iperf --help) there is a -B option.
That option will accept an IP address, then iperf will start
operating on the network interface with that IP address.

By default, the bmf0 interface is assigned the IP address of
the first OLSR interface (see README_BMF.txt). You can specify
the IP address that should be assigned to the bmf0 interface
via the plugin parameter PlParam "BmfInterfaceIp" , e.g.:

LoadPlugin "olsrd_bmf.so.1.6"
{
  PlParam "BmfInterfaceIp" "10.10.10.234/24"
}

You would then force iperf to use bmf0 by issueing 'iperf -B 10.10.10.234'

Please let me know if that works :)
