  • 第1题:

    What are two attributes of the Extended IS-Reachability TLV 22?()

    A. system-ID

    B. band-width

    C. wide-metrics

    D. authentication


    参考答案:A, C

  • 第2题:

    MIB中的信息用TLv形式表示,IP地址l92.168.2.3用TLV形式表示时,实际占用的字节数是 ( ) 。

    A.2
    B.4
    C.6
    D.8

    答案:C
    解析:
    基本编码规则(BER)将ASN.1表示的抽象类型值编码为字节串,这种字节串的结构为:类型——长度——值,简称TLv。其中,值部分还可以递归地再编码为TLv结构,以具有表达复杂结构的能力。 IP 地址l92.168.2.3使用ASN.1表示的结果是“40,4,192,168,2,3”,即实际占用6个字节数。其对应的BER编码结果是 28 04 c0 A8 02 03。其中,第一个字节“28”的二进制表示是00101000,最左边两位“00”表示通用标签(UNIVERSAL), 第3位“l”表示构造类型,剩余比特位“01000”是IP地址(IPAddress)类型的具体标签值;第二个字节“04”指明其后的“值 (Value)”部分长度为4个字节;第三个字节“c0”的二进制表示是l l00 0000,表示十进制数192;第四个字节“A8”的二进制表示是 l010 1000,表示十进制数168;第五个字节“02”的二进制表示是00000010,表示十进制数2;第六个字节“03”的二进制表示是 00000011,表示十进制数3。
