PART TWO:SUBNET CALCULATION Given the ClassB IP address,172.20.2.131/25 determine the following:- The number of bits borrowed - The Subnet ID,and subnet mask - The range of host addresses for this particular subnet Be sure to write your answers down PART THREE:WORKSTATION CONFIGURATION - Configure PC0 with the first usable IP address within the host range defined in Part two.- Configure PC1 with the second usable IP address within the host range defined in Part two.- Configure PC2 with the second to last usable IP address within the host range defined in Part two.- Configure PC3 with the last usable IP address within the host range defined in Part two.Test that all PCs can communicate with one another.上面说的是不是要求从172.20.2.131/25中划分4个IP地址啊!但是我划分了,CCNA的实验检测说我的IP地址不正确,请问高手是什么原因!补充:要求两用两台交换机和四台PC,每台交换机连接两台PC.

25位掩码的话 2进制就是 255.255.255.128 用255-128=127 可用地址从172.20.2.172.20.2.126 172.20.2.128~172.20.2.254 只要你地址在172.20.2.128~172.20.2.254段内 就可以的 你看看 无类域间路由 开了么
