OSPF - Area STUB multiple exit points
I am reviewing the following excersise:
I have a doubt regarding that. In the exercise they cover the problem of the ABR's loosing the connection to the area 1. But the excercise doesn't cover the failure of the connection from the ABR to area 0.
I mean, if the ABR is isolated and cannot reach the area 0, but it still has connectivity to the area 1, I have realized that in this situation, the ABR is still advertising a default route to the area 1, but the ABR is isolated, so some of the routers will lost its connectivity due to that.
Is there any solution to solve this problem in scenarios with two or more exit points in a stub or nssa area??
Thank you very much!
