• Question 193:

  Click the exhibit button A. The route policy should be applied as in import policy

  

  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)

  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.
