OSPF has been configured on all routers in the network. However, router R1 does not receive a
default route to router R2 as intended. Which configuration change would ensure that R1 would
receive a default route from R2?

A.
Add the area 1 stub command on routers R1.

B.
Add the always keyword to the default-information originate configuration command on router
R2.

C.
Remove the default information originate configuration command from router R2 and place it on
router R1.

D.
Add the ip route 5.0.0.0 255.255.255.0 0.0.0.0 command to router R2.

Explanation:
The point of this question is about advertise a default route into an ospf area.
There are two ways to advertise a default route into an ospf area. The first is to advertise 0.0.0.0
into the OSPF domain, provided the advertising router already has a default route. The second is
to advertise 0.0.0.0 regardless of whether the advertising router already has a default route. The
second method can be accomplished by adding the keyword always to the default-information
originate command. In this example, the “always” keyword would be required in order to propagate
this default route.
