corresponding to the MAC address in the table, copy the packet directly onto the port. Three-layer switch: three-layer switching technology is the technology of combining routing technology with Exchange technology. After the first data flow is routed, the it will generate a MAC address and IP address mapping table, when the same data flow through again, according to this table directly from the two layer through rather than again routing, thus eliminating the

eliminating the router routing and resulting in network delay, improve the efficiency of packet forwarding. Routers: Traditionally, routers work in the third layer of the OSI Seven layer protocol, whose main task is to receive packets from a network interface and, depending on the destination address contained therein, decide to forward to the next destination address. Therefore, the router must first find

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

The OSPF protocol is very important for the use of Cisco routers. But how do I perform specific operations? The following article will give a detailed explanation. OSPF protocol operation: 1. the ROUTER that declares OSPF sends a HELLO message from all interfaces that start the OSPF protocol. The two routers share a Public Data Link and can negotiate with each other the parameters specified in their HELLO packets. Then they become neighbors Neighbor)2

Early domestic ADSL line access are bridge mode, by ADSL modem and computer, in the computer to allocate fixed IP address, boot can access to the local terminal equipment into the Internet. However, when the user does not boot on the Internet, IP is not to be exploited, will cause the current increasingly scarce public network IP resources waste, so there has been a PPPoE dial-up ADSL access. PPPoE dial-up can enable the user on the power-on dial-up access to the local equipment, by the local e

The routing technology must also comply with the router standard in its application. Although the current router standard is not complete yet, it is believed that with the development of routing, it will also be more improved and stable. Vro supports multiple protocols, such as TCP/IP, IPX, SPX, and AppleTalk. Even the TCP/IP protocol has versions 4 and 6. However, due to the fact that TCP/IP has become a s

I have learned some useful things about the vro test. So I have studied the types and methods of the vro test. I would like to share them with you here, hoping to help you. With the rapid development of the information industry, computer network technology has been widely used. Computer networks have become an essential part of modern work and life. As the core device of the computer network, routers are widely used in the network. High-end router tes

With the development of wireless network, more and more companies and enterprises have begun to layout wireless LAN, today we mainly introduce the appropriate for small and medium-sized wireless router bridging or WDS capabilities. This article takes tp-link wr841n wireless router Setup as an example, and other router reference setup ideas to set up.As shown in a

Recently, I bought a new 705S wireless router, because my original wireless router is outdated, the following and netizens share the experience of the use of this router. Used to surf the internet quickly, online to see the movie very smooth, very few cards, download a few 10 trillion software 32 under the end, browsing the web is naturally not said, it is flyin

When the router is published, there are some technical terms, such as 802.11AC, 5G, gigabit, dual frequency, 2*2 antenna, Wi-Fi, and also the conclusion that "10 times times Faster", "Top Configuration", "Global X". Under the manufacturer propaganda, some people think that the product is good to be bad, also some people think the manufacturer is bragging x. This article is the wireless router knowledge popu

The wireless router is the transmission media, this article from the author's own TP-LINKWR641G as an example, describes the specific operation steps of the wireless router configuration, and describes the WAN port settings and other issues. As we all know in the tutorial on setting wireless routers, wireless signals are the carrier of data transmission, which means that the stability of wireless networks i

There is no fixed standard for understanding the Wireless Router Protocol. Generally, the standard is IEEE 802.11g. Other content of the wireless router is described in detail later. In our contact, these standards have little impact on us. Wireless Router Protocol Standard Currently, wireless routers support the IEEE 802.11g Wireless

When we use the Router device for networking, once encountered similar router device panic, the network is frequently dropped phenomenon, we can consider the router upgrade in order to timely fix the router system itself bugs, to ensure that the efficiency of the router more

Basic all routers on the shell will have a product nameplate, the above will be detailed labeling router login address, login account and password, the purchase of new router friends will often ask small knitting router login address, account number password, in fact, is in the immediate, but we are not good at observation, the following figure, We can see the Fi

I. Lab Objectives Master the configuration of Integrated routes; View the routes generated by route redistribution; Familiar with Wan cable connection methods; Ii. Lab background Assume that a company connects to the egress router R1 through a layer-3 switch, and router R1 is connected to another router R2. Layer 3 and R1 run the r12002 routing protocol, whi

When a computer sends information in a network, it splits the information into small fragments, called "data packets" or "data packets". These packages contain the target address. So after they enter the network, they can reach the correct target computer. If the target computer is located in another network, it must be forwarded (Route Selection) to the correct network through a router. How does a router w

Setting a wireless router is an important step to ensure the security and rationality of our network. As we all know, wireless signals are the carriers of data transmission, which means that the stability of wireless networks has a very direct relationship with wireless signals. In fact, to make a wireless router in a very stable state, you must make a series of reasonable wireless
