I've configured OSPF on 3 switches - Core and 2 access switches. All switches are in area 1.
I wish to propagate default route 0.0.0.0 from my core switch to access switch. But without area 0 configured on the core, the default route 0.0.0.0 cannot be propagated to the access switch. Therefore, I configured my Core switch as a NSSA ASBR to propagate default route to its switches. Is that the correct way to do it?
