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 defaultroute from R2?

A.
Add the area 1 stubcommand on routers R1.

B.
Add the alwayskeyword to the default-information originateconfiguration
command on router R2.

C.
Remove the default-information originateconfiguration command from router
R2 and place it on router R1.

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

Explanation:
The default-information originatecommand advertises a default route into a normal area,
provided the advertising router already has a default route. If we want the router to advertise
the default route even if it does not have a default route then we can append the keyword
alwaysafter the above command.
In this question, notice that R2 does not have a default route (something like this: ip route
0.0.0.0 0.0.0.0 6.0.0.2) so the “default-information originate” will not advertise this default
route to R1 -> We need to add the keyword “always” or declare a default route
