What will happen if I have 2 ABR on my area 0

Ching01

I just want to know which path will select if 2 ABR exists in same destination.

I didn't try yet on my home lab but can you tell me something about this scenario.

Thanks

If there are 2 paths to a destination via 2 abr's with the same cost to the destination the route will be load balanced.

Okay just got confused I remember OSPf can load balance equal cost routes not unqueal cost route.

Anyway, just one question regarding summary-address in ABR, I am confused with this example.

In NSSA R2 there is a configuration summary-address command and based on the books I am just now reading summary address is used by ASBR not ABR.

And you can see in my example the this NSSA R2 is ABR connecting two areas.

How could this happen?
ABR = area area ID range ip mask
ASBR = summary-address ip mask [not advertise] [tag]
