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?
A. The policy "reject" should be set for import rather than export.
B. This is not possible because OSPF cannot use import policies.
C. The policy was likely not "committed" after creation.
D. The prefix list reject should be "192.168.3.0/16 exact".
E. Router R1 should be configured as an OSPF "asbr".
正解：B

Routers R1 , R2, and R3 are running a classful routing protocol between them. Assuming that router R1 advertises all directly connected networks, how will these networks be represented in router R3's routing table?
A. Router R3's routing table will have one entry for 10.1.1.0/24 and one entry for 10.1.2.0/24.
B. The networks will be represented with one entry of 10.0.0.0/8 in router R3's routing table.
C. The networks will be represented with one entry of 10.0.0.0/24 in router R3's route table.
D. Router R3's routing table can only contain one of the routes, which will result in route flapping.
正解：B
