To make OSPF area 4 a totally stubby area, which two things need to be done? (Choose two.)

  • A. Apply the area 4 stub command to all routers in the area.
  • B. On the ABR, use the area 4 stub command with the no-summary keyword.
  • C. On the ABR, specify a default cost for the area with the area default-cost command.
  • D. On the ABR, use the default-information originates command to inject a default route into area 4.
Show Suggested Answer Hide Answer
Suggested Answer: E. Use the auto-cost command on each router in the area to automatically determine the cost to other OSPF areas. 🗳️
Explanation -
To make an area totally stubby we must apply the area area-id stub no-summary command on the ABR and area area-id stub commands to all other routers in that area.
Note: The ABR in a totally stubby area does not create Type 3 summary LSA. It only creates a default route to outside destinations.
