  • 交换路由中期测验20181205(DHCP、IOS、静态路由、RIP、EIGRP)

    测试拓扑:

    知识点:DHCP;IOS的备份恢复与更新;静态路由;动态路由(RIP);动态路由(EIGRP)

    1.DHCP

    拓扑:

    主要指令:

                  ip dhcp pool 地址池名称

                  network 网络号 子网掩码

    详细配置(参考答案):

    详细配置:

    int f0/0

    ip add 192.168.15.1 255.255.255.0

    no shu

    exit

    ip dhcp pool lilywhite

    network 192.168.15.0 255.255.255.0

    exit

    PC机下IP设置为DHCP自动获取IP地址,验证结果。

     

    2.IOS的备份恢复与更新

    拓扑:

    题目背景:

    进入1841路由器后显示rommon 1,显然只剩下最基础的bash环境了,需要通过Server0服务器上保存的IOS进行恢复的操作。

    操作步骤:

          tftpdnld(进入tftpdownload模式,从而方便查看参数

                   IP_ADDRESS=192.168.1.2

                   IP_SUBNET_MASK=255.255.255.0

                   DEFAULT_GATEWAY=192.168.1.1

                   TFTP_SERVER=192.168.1.1

                   TFTP_FILE=c1841-advipservicesk9-mz.124-15.T1.bin

                    (值得注意的是这里的文件名是从服务器copy下的文件名)

                   tftpdnld(再次进入tftpdnld模式查看)

                       (此时显示出参数信息,并询问是否下载IOS,并烧录,输入y开始烧录)

                   boot(烧录成功后,加载系统)

    值得注意的是:必须要先确认好Server0服务器的IP地址,否则无法与服务器联通,下载不了数据。

    3.静态路由

    拓扑:

    主要指令:

          ip   route   目标网络号   子网掩码   下一跳

    详细配置(参考答案):

    4.动态路由(RIP)排错

    拓扑:

    错误点:

    R10:

    RIP配置错误:宣告网络的主类号和RIP版本错误,没有关闭自动聚合。

    R11:

    F0/0和F0/1的IP地址配置错误;

    RIP配置错误:缺少宣告网络的主类号,没有关闭自动聚合。

    R12:

    缺少loopback接口的IP;

    F0/0接口的IP地址设置错误,F0/1接口上多了个IP地址;

    RIP配置错误:同上。

    更正后配置:
