    You are using IPv6， and would like to configure EIGRPv3. Which three of these correctly describe how you can perform this configuration？（）
    A

    EIGRP for IPv6 is directly configured on the interfaces over which it runs.

    B

    EIGRP for IPv6 is not configured on the interfaces over which it runs， but if a user uses passive-interface configuration， EIGRP for IPv6 needs to be configured on the interface that is made passive.

    C

    There is a network statement configuration in EIGRP for IPv6， the same as for IPv4.

    D

    There is no network statement configuration in EIGRP for IPv6.

    E

    When a user uses a passive-interface configuration， EIGRP for IPv6 does not need to be configured on the interface that is made passive.

    解析： 在java中一个类只能有一个直接父类，但是可以实现多个接口，在继承的同时可以实现接口，之所以取消多继承的原因是多继承使得代码产生很多问题,而使用单一继承则可以使代码更可靠。
