I have the following topology
I created an aggregate route on R2, then export to iBGP, I expect to see that route in IPS router.
Before I configured Area 1 to be nssa, it worked fine.
After I configured the following :
set protocols ospf3 realm ipv4-unicast area 0.0.0.1 nssa default-lsa default-metric 10
set protocols ospf3 realm ipv4-unicast area 0.0.0.1 nssa no-summaries
set protocols ospf3 area 0.0.0.1 nssa default-lsa default-metric 10
set protocols ospf3 area 0.0.0.1 nssa no-summaries
R2 still advertised that aggregate route
root@vMX-2# run show route advertising-protocol bgp 172.30.15.8
inet.0: 21 destinations, 21 routes (21 active, 0 holddown, 0 hidden)
Prefix Nexthop MED Lclpref AS path
* 172.30.0.0/16 Self 100 I
but R3 hides that route
root@vMX-3# run show route hidden extensive
inet.0: 11 destinations, 11 routes (10 active, 0 holddown, 1 hidden)
172.30.0.0/16 (1 entry, 0 announced)

Is that because the no contributing routes any more on R3, so that aggregate route is hidden ?
How to resolve this ?
thanks in advance !!!
