Refer to the exhibit. 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?
Select the best response.

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.
