R6为isp，接口IP地址均为公有地址；该设备只能配置IP地中，之后不能在对其进行其他任何配置

 

两台PC打开DHCH

 

IP地址分配如下

 192.168.1.0/24
192.168.1.000 00000/27---骨干
192.168.1.000 000 00/30 -- 192.168.1.0/30
192.168.1.000 001 00/30 -— 192.168.1.4/30
192.168.1.000 010 00/30 -- 192.168.1.8/30

192.168.1.101 00000/27 -- R5 -- 192.168.1.160/27

R1 R2 R4环回

R1两个环回LoopBack0 192.168.1.33/28 LoopBack1  192.168.1.49/28

R2两个环回LoopBack0 192.168.1.65/28  LoopBack1 192.168.1.81/28

R4两个环回LoopBack0 192.168.1.129/28 LoopBack1  192.168.1.145/28

R1-R5都可以访问R6的环回

 R6telnetR5的公有IP地址时，实际登录到R1上

R4与R5正常通过1000M链路，故障时通过100M链路 

 进入g0/0/2 开销为60  因为给下面的路的开销为70所以在0/0/2接口正常时下面的100M不用  当上面故障时那么70就成为最小开销。
