静态路由复习实验

news2024/11/20 18:21:54

实验分析：

1 .R6为isp,接口IP地址均为公有有地址；该设备只能配置IP地址, 之后不能再对其进行任何配置;

r6只能配置IP，所以r1--r5上需要配置指向r6的缺省路由；

2 .R1—R5为局域网,私有P地址192.168.1.6/24,请合理分配;

图中骨干链路只需俩个IP，因此分配/30的网段即可，r1,r2,r4的俩个环回用大的网段划分成俩个小网段（减少黑洞路由的出现），然后按须分配。

3.R3下的两台PC通过DHCP自动获取IP地址;

r3下启动DHCP服务

4.选路最佳,路由表尽量小,避免环路;

选路最佳需配置负载均衡，且经过的路由数目尽量少；

路由表尽量小则需进行汇总，与缺省路由通向的网段可省略；

避免环路需进行空接口配置。

5.R1—R5均可以访问R6的环回；

R1-R5为内网，R6为公网，需在边界路由器R5上配置nat服务(EASYIP)

6. R6 telnet R5的公有IP地址时,实际登陆到R1上;

R1上开启telnet服务，R5配置nat映射到R1的任意接口即可

7. R4与R5正常通过1000M链路,故障时通过100M链路;

R4与R5之间配置浮动静态路由，修改优先值。
