[j-nsp] routing instances - ospf - summarization

[n f]

Hi all, 


I'm running junos 11.4 on a cluster of srx devices. 


I'm using two virtual instances, one for my internal networks and internet, and another one for a private network. 


OSPF is configured on routing instance1 (RI1) and routing instance 2 (RI2).

I can export between routing instances, but I'd like to know if it was possible to export via ospf from RI2 to other physical routers
a single route that summarizes all the local routes I have. (like 10.10.0.0/16, as all the routes I receive via ospf on RI2 from RI1 

are included within this subnet). 


Does anyone know if it is possible to do so ? (maybe OSPF doesn't allow that at all). 


thanks
