[j-nsp] Problem with OSPF route summarization

Are you redistributing the subnetworks into OSPF?  If I'm not mistaken,
OSPF area summaries will not summarize external routes (the
redistributed routes), unless you are summarizing the routes in Area 0.

	Hi all

	I am having problem with route summarization in an NSSA area.
Here is my configuration

	 

	area 0.0.0.300 {

	    nssa {

	        default-lsa default-metric 1;

	        no-summaries;

	    }

	    area-range 10.10.0.0/19;

	    area-range 192.168.1.0/24;

	    authentication-type md5

	    interface ge-0/3/0.102 {

	        metric 1;

	        

	All the routers in area 0.0.0.300 are redistributing static into
OSPF and the juniper is sending two summary blocks into area 0. But the
routing tables of any area0 router is still showing smaller subnets
instead of just summarized routes ie 10.10.0.0/19 and 192.168.1.0/24.
Looks like the juniper is not doing the right thing and it is
propagating all the routes from area 0.0.0.300 to area0. The version of
code I am running is 5.3R1.2. Does anyone know what I have done wrong in
the configuration or there is a bug in the code.

	Thanks in Advance

	Waj
