Because of the continuous advancement of social informatization, people's demand for data communication is increasing. Since the launch of TCP/IP protocol cluster in the 70 's, it has developed into the fact standard of Network layer communication protocol, and the Internet based on TCP/IP has become the largest and most important network. As the core equipment of IP network, routers have been widely used.
As the core equipment of IP network, the technology of
inaccessible. Every 30 seconds, the distance vector routing protocol sends the entire route selection table to the adjacent site to update the route selection table of the adjacent site. In this way, it can collect a list of networks from other sites (directly connected or connected in other ways) for route selection. Distance Vector Routing uses the number of hops as the metric value to calculate the number of routers that need to pass to the destination.
For example, r I p uses the B e l m a
For wireless networks, we always focus on the routing configuration. So here we will summarize the detailed description of the wireless router configuration. Before configuring a wireless router to configure a wireless router, you must connect C to the wireless router with a network cable. the other end of the network

Many people may not have a special understanding of Enterprise routers. The following describes the related knowledge about enterprise routers. The popularization of the Internet not only brings a wealth of online resources to most SMEs, but also brings informatization into enterprises, which has dramatically changed the traditional operation mode of enterprises.
The scientific and standardized use of the network by enterprise members is directly related to the utilization efficiency of this res

For everyone in the process of using the router encountered problems, small series I think it is necessary to popularize some of the router's small knowledge, I believe that as long as you carefully read, you will suddenly see the internet is no longer difficult!!

This article describes the basic working principles of routers in TCP/IP networks, introduces several functions of IP routers, and provides Static Routing and dynamic routing protocols, as well as the concept of the internal gateway protocol and the external gateway protocol, and briefly introduces the most common RIP, OSPF, BGP and BGP-4 routing protocols, then, it describes the design objectives and types of routing algorithms, and focuses on the link state method and distance vector method.

What does router hijacking mean?
Router hijacking, usually refers to the wireless network in the radio router, other users by cracking the wireless network password, thereby connecting to your wireless network, and then through the login router management interface to control the entire wireless network.
In layman's
When information needs to be transferred between two networks, the interconnection device of common routers is responsible for the transmission of data. The main work of the router is: The decision of the path and the forwarding of the packet (from the router an interface input, and then select the appropriate interface output); Maintenance path by the table.The way the
Tp-link routers cannot connect to the Internet a workaround
Tp-link wireless router, model "tl-wr841n", can be used yesterday, whether it is wireless or local connection. Today is suddenly unavailable, wireless and local are dead, the display cannot connect to the Internet. Reset key pressed over, reboot, and even restore factory reset. Not yet. Angry half to death. What the hell is going on here? (Also, the wireless

On the Internet to see how to prevent the problem of hijacked routers is very good, it is true that we use the router at the same time should be prevented from being hijacked to protect our privacy and property security. Today, I share my personal experience of preventing routers from being hijacked.

At present, China's wireless routers are developing rapidly, and there are also many problems. The following describes the problems that wireless routers often encounter during the connection process and gives you a detailed analysis. With the popularity of wireless networks, wireless routers gradually enter our lives. However, if you purchase a wireless router, in addition, you must also use the original wired wireless
The communications department allows each broadband user to use two computers to share the Internet, and the user needs to install a broadband router. So, what kind of router should be purchased more appropriate?

Generally speaking, the router is establishes the LAN and the WAN Connection bridge, but at present the backup router's application is very widespread, simultaneously its function also more prominent. Cisco routers have a variety of backup technologies, today I will introduce the router's own backup technology and line backup technology.
First, the router backup technology

update from an adjacent site within 9 0 seconds, it does not consider the neighboring site unreachable. Every 30 seconds, the distance vector routing protocol will send the entire routing table to the neighboring site, so that the routing table of the neighboring site is updated. In this way, it can collect a list of networks from other sites (directly connected or otherwise) to make routing choices. The distance vector routing protocol uses the hop count as a measure to calculate the number of
