Typically such a decission should be made by the host, not by the local node. 
OLSRv2 solves this in the current draft by allowing linklocal-IPs as 
originators to tell all nodes "this is just an id-string, not a routable 

On the other side it might be possible to "compress" the routing table, but 
that makes deleting routes more difficult.

I could imagine it should be possible (for IPv6) to add a configuration option 
that OLSRd always set up a /64 route towards the originator, but that's more a 
hack than a sollution.
