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

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:
