B.

An OSPF network needs at least one area border router to function.

C.

Area border routers connect the backbone area to other areas in an OSPF network.

Question 13

Click the exhibit button.

Router R2 advertises the network 192.168.3.0/24 to router R1 via OSPF. A route policy has been constructed to discard the route on router R1; however, it is not working. What is the problem?

Options:

A.

The prefix list reject should be "192.168.3.0/16 exact".

B.

Router R1 should be configured as an OSPF "asbr".

C.

The policy "reject" should be set for import rather than export.

D.

The policy was likely not "committed" after creation.

E.

This is not possible because OSPF cannot use import policies.
