Question # 80

Click the exhibit button

The 192 168 3.0/24 network is learned on router R1 via IS-IS Given the OSPF configuration shown, and assuming that the OSPF adjacency between routers R1 and R3 is up, why is the 192 168.3.0/24 route not in router R3 ' s route table? (Choose two)

A.

The route policy should be applied as in import policy

B.

The no-redistribute-external command is used on router R1

C.

The route policy is incorrect. It should say " from protocol ISIS " rather than " from protocol direct " .

D.

It is not possible to be an ASBR and an NSSA. The ASBR configuration should be removed.

E.

The interface between routers R1 and R3 needs to be in OSPF area 0 rather than OSPF area 1 because a backbone area must always exist.
