如何实现网络分段之妙招（How to realize the coup of network segmentation） Beida Jade Bird Changping campus offers To implement network segmentation, you can use routers, firewalls, and three layer switches with a virtual local area network (VIAN) function. How can network segmentation be achieved without these devices? Here are three economical and reliable methods for network segmentation without any of the above devices. With the rapid growth of the number of computers in the campus network, the problems of computer management and computer security are becoming more and more prominent. In the early stage of network usage, because of the small number of information, we only need to set up a subnet, there is no segmentation of the network, and with the increase of users, we must take measures to strengthen the management of network segmentation. Staged management of the network, not only for the network maintenance, but also can reduce the scope of the collision domain, isolated segment within the broadcast storm, so as not to affect other users in the network, improve the stability of the network and the actual bandwidth available. Multiple network card host soft routing This is done by installing multiple blocks of network cards on the Windows 2000 Server, using the router function of Windows 2000 Server to segment the network. Well, heres how to build two network segments (the implementation of multiple network segments), and introduce the implementation method. Suppose we want to build two segments: the address of the segment A is ; the address of the segment B is . They are all C class subnets (the first three segments of the IP address are fixed, the last one is arbitrary), and the subnet mask is . The two network segments are now connected by two network cards installed on the host. The network connection diagram is shown in figure 1. 1. Host settings To host Windows 2000 Server, for example, the specific implementation steps are as follows. ? 1. install and set up the n
