You have configured an OSPF stub area. The routes in the stub area require external reachability.
Which statement explains how OSPF meets this requirement?
A.
The ABR will generate a 0.0.0.0/0 martian route in the area.
B.
The ABR will flood Type 5 LSAs into the area.
C.
The ABR will flood Type 7 LSAs into the area.
D.
The ABR will generate a 0.0.0.0/0 default route in the area.
Explanation:
Reachability for routes external to OSPF is achieved via a 0/0 default route injected by the ABR.
