Multilayer Switching (MLS) is an Ethernet-based route exchange technology that provides a layer-3 Switch with an existing router. This article includes IP-only MLS; ipx mls and multicast MLS are out of the scope of this article. A traditional router typically performs two main functions: rewrites the Media Access Control (MAC) address based on the route table and information packet exchange route processing

Before launching various "hacker behaviors", hackers will take various measures to detect (or "detect") The host information of the other party, in order to determine the most effective method to achieve your goal. Let's see how hackers know the most basic network information-the IP address of the other party, and how users can prevent their own IP

Our lan has more than 100 computers. to distinguish different users from assigning more detailed access permissions, we use a fixed IP address instead of Automatically Obtaining an IP address, in addition, we need to connect some of them to the Internet. In this case, we nee

may not be in harmony with the address range you have already used. For example, suppose your network uses a 190.160.25.x address range (I just made up a set of numbers) before any wireless access point is installed. If so, there are two reasons why a wireless access point assigning user 192.168.0.x addresses can cause problems. To avoid the problem of wireless network

Introduction:I have recently conceived a practical training book. The VM environment needs to be used for system experiments. This involves the IP settings of the host machine and the client. In the future, the reader's network environment is very different, but the client needs to be able to connect to the external network. This facilitates the experiment, and the IP
