It's not clear from your diagram which routers are in which areas ?
But if R2/R3 are ABRs that suggest R4 is in a different area than R1. Can you not just make R4's area a stub or totally stubby area and then the ABRs would generate a default route into that area for you.
I have put a diagram here R2/R3 are acting as ABR here.You can considerd R2 and R3 as two Different Data Centre
Problem is We are preffering R2 as primary Path path and R3 as secondry path.
Some of the applications are coonecting to R2 and some Conencting R3 by creating stub/totaly stub we have default route but towards priamry path only.So if traffic want to use R3 datacentre apps it will take R2 as prefered path which i dont want so in our case stub/totaly stub wont work.
Okay, i'm not understanding this. If R1 is receiving a default route from the internet then why not have it do the default-information originate and then it would send a default route to R2/R3 who would then send it to R4.
