OSPF设计为支持可变长度子网掩码。
OSPF was designed to support variable-length subnet masking (VLSM).
子网掩码由四个字节组成，它的值为255时表示IP地址中网络地址的部分，值为0时则识别IP地址中表示主机号的部分。
The subnet mask is an octet that USES the number 255 to represent the network address portion of the IP address and a zero to identify the host portion of the address.
对于本例来说，可以将IP地址设置为192.168.128.1，将子网掩码设置为255.255.255.0。
For this example, set the IP address to 192.168.128.1 and the subnet mask to 255.255.255.0.
IP地址的主机地址部分里的所有字节都被设置为0。请输入一个有效的IP地址和子网掩码组合。
All of the bits in the host address portion of the IP address are set to 0. Please enter a valid combination of IP address and subnet mask.
IP地址的网络地址部分里的所有字节都被设置为0。请输入一个有效的IP地址和子网掩码组合。
All of the bits in the network address portion of the IP address are set to 0. Please enter a valid combination of IP address and subnet mask.
IP地址的网络地址部分里的所有字节都被设置为0。请输入一个有效的IP地址和子网掩码组合。
All of the bits in the network address portion of the IP address are set to 0. Please enter a valid combination of IP address and subnet mask.
