[j-nsp] Problem with OSPF route summarization

[Matt Leonards]

Hi Eric,

I believe you can only summarise directly on the ASBR (the ex-internal
router where redistribution into OSPF is taking place), but if you want to
have all the externals in the internal area, you could make the area an
NSSA. Then summarising on the ABR by doing what Josef suggested, with the
NSSA area-range commands. 

HTH.

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
