[j-nsp] Missing OSPF routes in ABR

[Alex]

Ihsan,
You may wish to contact Your provider P to explicitly configure non-matching 
domain-ids on P1 and P2 (if P1 and P2 are Juniper routers) in order to have 
the R5 routes advertised as Type-5 LSA to R4:
http://www.juniper.net/techpubs/software/junos/junos80/swconfig80-routing/html/instance-config24.html#1051716
AFAIK, Cisco routers assign the ospf process number as domain-id.
HTH
Cheers
Alex
