Hi everyone
Is it possible to have two asbrs on two areas which advertising default route to their areas. for example R1 is in area 0 and has default route to internet and advertise default route to area 0. R2 is in area 1 and advertise default route to area 1 and these areas doesnt receive any default route from each other.
how can I do that?

Hello @ectssamsectssams5825 ,
make area 1 an NSSA area then also have the R60 to advertise an LSA type 7 with no-propagate option so that ABR will not translate it to area 0
Hope to help

Hello,
do you mean ASBRs or ABRs ? Post a schematic drawing showing what you want to accomplish.

I mean Asbr.
default route for area 0 R61
default route for area 1 R60

config
default-information originate metric-type 1
this make internal in Area 0 select the default toward ASBR area 0
and internal in Area 1 select the default toward ASBR area 1
metric-type 1 cost is equal to sum of all link cost to ASBR.

but if R61 fails, area 0 use R60 as default route and whole traffic goes to R60

you will get redundancy also.
but NSSA is complete isolate the area default gateway.
