  • 第1题：

    Refer to the exhibit. Will redistribute d RIP routes from OSPF Area 2 be allowed in Area 1? ()

    A. RIP routes will be allowed in Area 1 only if they are first redistributed into EIGRP.

    B. Because NSSA will discard type 7 LSAs, redistributed RIP routes will not be allowed in Area 1.

    C. Redistrib uted RIP routes will be allowed in Area 1 because they will be changed into type 5 LSAs in Area 0 and passed on into Area 1.

    D. Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 7 LSAs in Area 0 and passed on into Area 1.
