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.
Answer: B
Explanation
The default-information originate command 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 always after 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 -> B is correct.
