That's because there is no quick fix.

I thought it to be that simple as well; it is not see below:

This does not work because zebra marks the OLSR kernel routes as 
inactive.  Quick fix is to hack the zebra daemon; real fix is to 
implement a zebra client in OLSRd to talk to zebra.  You want to take 
the HNA4 set from OLSRd (implement a module) and send them to zebra 
(using the Z-protocol).

I have some example code for this; but nothing mature enough to be 
deployed in any live network.

This is a real stumble block for OLSRD deployment IMHO; anyone whishing 
to deploy this (with dynamic redistribution) in a network where OSPF is 
the IGP is out of luck currently...
