Unable to bind NDB to an interface

I have a problem forcing the NDB to bind to an interface.

I have the following setup, two NDB machines which are connected using 2 network interfaces which are balanced using OSPF as routing protocol.
The shared ip which a want to bind to is located on an 'dummy' (non fysical) interface.
This IP is reachable thru one of the 2 fysical interfaces, with OSPF which makes sure at least one of the interfaces is routable.

dummy0
/ \
eth0 eth1

The problem is that whatever i try to do with the NDB deamons they just bind to all interfaces and use the first available routing entry which is in most cases the eth0.
So when the NDB connects to the Management deamon it uses this address as originating address, and the MGMD rejects the session (as one would expect).

Is there any way to force the NDBD to bind to an interfaces, in this case a non fysical interface, the dummy0 ?
